HMC1114PM5E RF Power Amplifier for Radar and Wireless Transmitters

ElecSuppliers ApplicationsOct 10, 2026

The HMC1114PM5E is a gallium nitride (GaN) broadband RF power amplifier from Analog Devices, designed for transmitter systems that require substantial output power across the 2.7 GHz to 3.8 GHz frequency range. With typical output power of 42 dBm, typical small-signal gain of 34.5 dB, and power-added efficiency of up to 55% under specified conditions, this device is intended for demanding RF amplification applications.

The HMC1114PM5E is suitable for pulsed and continuous-wave (CW) operation. Its specified applications include wireless infrastructure, public mobile radio systems, commercial and military radar, test and measurement equipment, and general-purpose transmitter amplification.

For engineers selecting an RF power amplifier, the important considerations extend beyond output power alone. Frequency coverage, gain behavior, efficiency, bias requirements, thermal design, and RF matching all influence whether the HMC1114PM5E fits a particular transmitter architecture.

Understanding the HMC1114PM5E RF Performance

2.7 GHz to 3.8 GHz Operating Frequency

The HMC1114PM5E operates across an instantaneous bandwidth range of 2.7 GHz to 3.8 GHz. This makes it a candidate for RF systems whose operating frequencies fall within this specified range.

Frequency compatibility should be evaluated at the system level. Engineers need to consider the required operating channel, filtering, matching networks, transmission-line layout, and other components in the RF signal chain. A broad amplifier frequency range does not automatically mean that every complete transmitter configuration will deliver the same output power, efficiency, or linearity across the entire band.

42 dBm Typical Output Power

The device provides typical output power of 42 dBm at an input power of 18 dBm under the manufacturer's specified test conditions. This output level is equivalent to approximately 15.8 W, while the product is generally described as a greater-than-10-W GaN power amplifier.

This capability is relevant to transmitter designs that require a high-power amplification stage. Actual performance depends on operating frequency, drive level, bias conditions, load impedance, and thermal conditions. Engineers should use the datasheet performance curves rather than assuming that the headline output figure applies to every operating point.

34.5 dB Typical Small-Signal Gain

The HMC1114PM5E features typical small-signal gain of 34.5 dB. This gain characteristic helps designers evaluate the amplifier's position within a transmitter chain and estimate the required drive level from preceding RF stages.

Small-signal gain should not be treated as the expected gain at maximum output power. As the amplifier approaches compression, its large-signal behavior changes. Driver selection, gain distribution, output power requirements, and linearity targets should therefore be assessed together during circuit design.

Power-Added Efficiency up to 55%

The specified power-added efficiency reaches 55% under the manufacturer's stated conditions. Efficiency is important in RF equipment because the amplifier's DC power consumption contributes to the system's total energy demand and heat generation.

The actual efficiency depends on output power, frequency, input drive, bias conditions, and operating mode. System designers should examine the applicable datasheet curves and calculate power dissipation under realistic operating conditions before finalizing the power supply and cooling arrangement.

HMC1114PM5E Applications in RF System Design

Radar Transmitter Amplification

The HMC1114PM5E is specified for commercial and military radar applications. Its high RF output capability and support for pulsed or continuous-wave operation make it relevant to radar transmitter architectures that require power amplification within the device's frequency range.

A radar design must account for pulse duration, duty cycle, transmit frequency, output power, spectral requirements, and thermal behavior. The selected operating mode and external bias-control circuitry must follow the manufacturer's recommended implementation. The amplifier should be evaluated against the complete radar system requirements rather than selected solely on its maximum output power.

Wireless Infrastructure Equipment

Wireless infrastructure is another specified application for the HMC1114PM5E. In a wireless transmitter, an RF power amplifier increases the signal level before the signal reaches the output filtering and antenna interface.

The device's 2.7 GHz to 3.8 GHz frequency range can be relevant to infrastructure designs operating within that range. Compatibility still depends on the system's allocated frequencies, modulation characteristics, output power requirements, and regulatory constraints. The complete RF chain must also be evaluated for gain flatness, distortion, and unwanted emissions.

Public Mobile Radio Systems

The manufacturer identifies public mobile radio as an application, including systems that benefit from extended battery operation. For these designs, power-added efficiency and the overall power budget are important selection criteria.

Engineers should evaluate the amplifier alongside the available supply voltage, operating duty cycle, required transmission range, and thermal limits. The device's specified 28 V supply and bias requirements must be incorporated into the equipment's power architecture.

RF Test and Measurement Equipment

RF test systems may require a power amplifier to provide a suitable signal level for device characterization, subsystem testing, or laboratory measurements. The HMC1114PM5E can be considered when the required operating frequency and power level match its specified performance.

The test setup should include appropriate impedance matching, calibrated measurement equipment, and suitable attenuation or protection for downstream instruments. Measurement accuracy and repeatability depend on the complete setup, not just the amplifier's nominal specifications.

Key Design Considerations for HMC1114PM5E

Power Supply and Bias Control

The HMC1114PM5E specifies a 28 V drain supply at a quiescent current of 150 mA. The bias network must follow the manufacturer's recommendations for the device's operating mode and electrical limits.

GaN RF amplifiers can require careful bias sequencing and gate-voltage control. Designers should review the datasheet before applying power, particularly in pulsed systems where the timing of bias and RF signals affects operation. An appropriate bias controller may be needed depending on the intended circuit architecture.

RF Layout and Impedance Matching

RF layout is a critical part of implementing the HMC1114PM5E. The manufacturer's evaluation-board guidance specifies 50-ohm impedance for RF signal lines and direct connection of the package ground leads and exposed paddle to the ground plane. Sufficient vias should connect the top and bottom ground planes.

Poor grounding, uncontrolled transmission-line impedance, or unsuitable matching networks can reduce performance and affect stability. The PCB stack-up, copper geometry, component placement, and ground-return paths should therefore be reviewed as part of the RF design process.

Thermal Management

High-power RF amplification generates heat that must be removed through the package, PCB, and surrounding thermal structure. Junction temperature is an important consideration for long-term device reliability.

Thermal analysis should account for DC power consumption, RF output power, operating efficiency, duty cycle, ambient temperature, and PCB thermal characteristics. The design should remain within the manufacturer's specified operating limits under the intended worst-case conditions.

Pulsed and Continuous-Wave Operation

The HMC1114PM5E supports pulsed and CW applications, but the implementation requirements can differ significantly. Pulsed systems must account for pulse timing, bias sequencing, transient behavior, and duty cycle. Continuous-wave designs require evaluation of steady-state power dissipation and junction temperature.

The intended operating mode should be established early in the design process so that the power supply, bias circuit, thermal solution, and RF layout can be selected accordingly.

HMC1114PM5E Package and Integration

The HMC1114PM5E is supplied in a 32-lead LFCSP_CAV package measuring 5 mm × 5 mm. Its compact package can support integration into space-constrained RF assemblies, provided the PCB layout and thermal design meet the device requirements.

Package selection alone does not determine the ease of integration. Engineers should review the pin configuration, exposed-paddle grounding, land pattern, RF routing, and mechanical constraints before designing the final PCB footprint.

For design validation, the manufacturer's evaluation-board information and available S-parameter resources can help engineers assess RF behavior and develop a suitable implementation. Simulation results should be verified through measurements on the actual circuit board.

HMC1114PM5E Datasheet and Component Selection

Before approving the HMC1114PM5E for a new design, engineers should confirm the operating frequency, required RF output power, gain requirements, efficiency target, bias conditions, package footprint, and thermal constraints.

The official datasheet provides the detailed electrical specifications, operating conditions, performance curves, and implementation guidance required for design verification. These details are particularly important when the amplifier will operate near its maximum output level or under demanding pulsed conditions.

When evaluating possible alternatives, do not assume that another GaN power amplifier is a direct replacement simply because it supports a similar frequency range or output power. Pin configuration, bias requirements, RF matching, package dimensions, stability, and large-signal performance must all be compared before substitution.

The HMC1114PM5E is also listed separately from the HMC1114PM5ETR orderable variant. Buyers should verify the exact part number and required packaging format against the bill of materials before placing an order.

Sourcing HMC1114PM5E for RF Projects

Sourcing the HMC1114PM5E requires verification of the complete manufacturer part number, package configuration, product documentation, and supplier traceability. RF power amplifiers are application-specific components, so procurement teams should ensure that the supplied part matches the design's electrical and mechanical requirements.

Price and availability may vary by supplier, order quantity, and market conditions. Buyers should request current quotations and verify lead time, packaging details, traceability documentation, and applicable quality requirements before committing to a purchase.
