71 GHz to 76 GHz, E-Band Power Amplifier With Power Detector

The HMC7543 is an integrated E-band gallium arsenide (GaAs), pseudomorphic (pHEMT), monolithic microwave integrated circuit (MMIC), medium power amplifier with a temperature compensated on-chip power detector that operates from 71 GHz to 76 GHz. The HMC7543 provides 21.5 dB of gain, 25 dBm of output power at 1 dB compression, and 26.5 dBm of saturated output power at 20% power added efficiency (PAE) from a 4 V power supply. The HMC7543 exhibits excellent linearity and is optimized for E-band communications and high capacity wireless backhaul radio systems. The amplifier configuration and high gain make it an excellent candidate for last stage signal amplification before the antenna. All data is taken with the chip in a 50 Ω test fixture connected via a 3 mil wide × 0.5 mil thick × 7 mil long ribbon on each port.
