71 GHz to 76 GHz, 1 Watt E-Band Power Amplifier With Power Detector

The ADMV7710 is an integrated, E-band, gallium arsenide (GaAs), pseudomorphic, high electron mobility tranfer (pHEMT), monolithic microwave integrated circuit (MMIC), medium power amplifier with an on-chip, temperature compensated power detector that operates from 71 GHz to 76 GHz. The ADMV7710 provides 24 dB of gain, 28 dBm of output power at 1 dB compression, and 29 dBm of saturated output power at 20% power added efficiency from a 4 V power supply. The ADMV7710 exhibits excellent linearity and is optimized for E-band communications and high capacity, wireless backhaul radio systems. The amplifier configuration and high gain make the device 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. The ADMV7710 is available in a 40-pad bare die (CHIP) and operates over the −55°C to +85°C temperature range.
