摘要

The design and test of an E-band (81–86 GHz) down-converter mixer for satellite communications is given in this contribution. The selected topology is the sub-harmonically pumped mixer. The MMIC is designed with VMS's 100 nm GaAs pHEMT technology. Characterization of the mixer shows 13–16 dB conversion loss, 40 dB rejection to LO pump and other intermodulation products at IF port, and simulated IIP3 of +14 dBm.
