Overview
The HMC1121LP6GE is a high-performance, 4 W gallium arsenide (GaAs) pseudomorphic high electron mobility transfer (pHEMT) monolithic microwave integrated circuit (MMIC) power amplifier produced by Analog Devices Inc. This amplifier operates within the frequency range of 5.5 GHz to 8.5 GHz, making it ideal for high-capacity point-to-point and point-to-multipoint radio systems. The HMC1121LP6GE is characterized by its high saturated output power, excellent linearity, and integrated temperature-compensated on-chip power detector.
