HMC341

Overview

The HMC341 is a GaAs MMIC Low Noise Amplifier (LNA) designed for the 24 to 30 GHz frequency range. It operates on a single 3 V supply with a typical current consumption of 30 mA. The device provides a gain of 13 dB and achieves a noise figure of 2.5 dB. Key performance metrics include a P1dB compression point of 6 dBm and an OIP3 of 16 dBm. Input return loss is typically 13 dB, with power dissipation at 310 mW. It supports operation from -55°C to +85°C.

Procurement Notes

Verify specific ordering suffixes such as SX or LC3BTR against design requirements, as these indicate distinct packaging formats like gel packs or surface-mount QFNs. Confirm availability status directly with Analog Devices, as distribution channels may report limited stock or restricted supply conditions for this component.

Selection Notes

Select the HMC341 when designing circuits requiring minimal noise addition in the 24–30 GHz band. Ensure the PCB layout accommodates the specific package type chosen, whether bare die for MCM integration or SMT variants. Verify that the system power budget aligns with the 3 V, 30 mA operating parameters.

Part Context

This component belongs to Analog Devices' portfolio of GaAs MMICs targeting millimeter-wave frequencies.
