Abstract :
An S-band GaAs PHEMT MMIC receiver front-end which uses a novel monolithic mixer has been designed by using OmniSys and LIBRA software tools and developed in a 3 inch GaAs process at NEDI. The whole circuit provides 50.5±0.5 dB conversion gain with less than 1.5 dB noise figure in the 2.0-2.5 GHz frequency band. Only 0 dBm LO power of the mixer was consumed in this MMIC front end
