HEMT MMIC chip set for low cost miniaturized EHF SATCOM transceiver

Presented is a set of passivated pseudomorphic InGaAs HEMT MMICs for insertion into a low cost miniaturized transceiver for EHF SATCOM terminal applications. A 20 GHz MMIC balanced LNA with 1.8 dB noise figure and 31 dB gain, a K-Band downconverter, and a 22 GHz doubler chain are for insertion into...

Description
Summary:Presented is a set of passivated pseudomorphic InGaAs HEMT MMICs for insertion into a low cost miniaturized transceiver for EHF SATCOM terminal applications. A 20 GHz MMIC balanced LNA with 1.8 dB noise figure and 31 dB gain, a K-Band downconverter, and a 22 GHz doubler chain are for insertion into the receiving subsystem. The 22 GHz doubler chain, a 44 GHz doubler chain, and a 44 GHz driver amplifier with +21 dBm of output power are for insertion into the upconverter-transmitter subsystem. The 22 GHz doubler chain and 44 GHz driver amplifier feature couplers and diode detectors integrated on-chip for built-in-test (BIT) application.< >
