Overview
The HMC8142 is an integrated E-band gallium arsenide (GaAs), pseudomorphic high electron mobility transistor (pHEMT), monolithic microwave integrated circuit (MMIC) medium power amplifier. It operates within the frequency range of 81 GHz to 86 GHz and is optimized for E-band communications and high capacity wireless backhaul radio systems. The amplifier features a temperature-compensated on-chip power detector and is designed for excellent linearity and high gain, making it an ideal candidate for last stage signal amplification before the antenna.
