Overview
The HMC637BPM5E is a high-performance, gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) power amplifier designed by Analog Devices Inc. This device utilizes pseudomorphic high electron mobility transistor (pHEMT) technology and operates as a cascode distributed power amplifier. It is self-biased in normal operation and offers optional bias control for adjusting quiescent current and optimizing second-order and third-order intercept points (IP2 and IP3). The amplifier is suitable for a wide range of frequencies from DC to 7.5 GHz, making it ideal for military, space, and test equipment applications.
