HMC994APM5ETR-R5

Overview

The HMC994APM5ETR-R5 is a GaAs pHEMT MMIC distributed amplifier manufactured by Analog Devices Inc. It operates within a frequency range of 0 Hz to 28 GHz, providing a typical gain of 16 dB. The device requires a 10 V supply voltage and draws 250 mA of current. Key performance metrics include a noise figure of 4 dB, a P1dB compression point of 27 dBm, and an OIP3 of 36 dBm. It features an input return loss of 12 dB and dissipates up to 3.5 W of power. The component is housed in a compact LFCSP-32 surface-mount package and is rated for operation between -40°C and +85°C.

Feature Summary

• Utilizes GaAs pHEMT technology for high-frequency distributed amplification
• Provides wideband coverage from DC to 28 GHz with consistent gain
• Integrates on-chip termination for simplified RF interface matching

Applications

• Test and measurement equipment requiring broadband signal amplification
• Electronic warfare systems needing wideband signal processing
• Military radar subsystems operating in high-frequency bands

Procurement Notes

Verify the specific suffix R5 against the official Analog Devices datasheet to confirm reel packaging specifications. Ensure the LFCSP-32 thermal pad connection meets your PCB layout requirements for adequate heat dissipation given the 3.5 W power dissipation rating. Confirm RoHS compliance status through the manufacturer's environmental documentation before final integration.

Selection Notes

Select this component when a wide bandwidth extending to 28 GHz is required alongside moderate output power capabilities. The 16 dB gain and 4 dB noise figure make it suitable for intermediate stages in receiver chains. Consider the 10 V supply requirement and 250 mA current draw during power budget planning. The LFCSP-32 package offers a balance between thermal performance and board space efficiency for dense designs.

Part Context

This part belongs to the HMC994 series of distributed amplifiers designed for high-performance RF applications. It represents Analog Devices' capability in GaAs MMIC technology for ultra-wideband signal conditioning. The APM5ETR-R5 designation indicates the specific tape-and-reel packaging variant intended for automated surface-mount assembly processes.

Replacement Considerations

Consult the official Analog Devices replacement guide for verified cross-reference part numbers. Do not assume functional compatibility with other HMC series amplifiers without verifying pinout and electrical parameter alignment.
