Analog Devices announced a pair of high-performance gallium nitride (GaN) power amplifier (PA) modules which offer one of the highest power-density levels in their class, thus minimizing size and weight of the subsystem. The HMC7885 and HMC7748 broadband modules target applications operating between 2 GHz and 6 GHz, including test and measurement, communications, Traveling Wave Tube (TWT) replacement, military/aerospace surveillance and countermeasures, and radar. The fully integrated, all solid-state devices expand ADI's existing line of GaN-based PAs, and feature ease of use to accelerate prototyping and system design.
The HMC7885 is a 32-W, hermetically sealed, hybrid amplifier housed in a hermetic flange-mount package for high-reliability applications. This hybrid amplifier typically provides 21 dB of small-signal gain and 45 dBm of saturated RF-output power. The device draws 2.2 A of quiescent current from a 28-V dc supply. Both RF input and output are DC blocked and matched…
