Abstract :
New results obtained on two Ka Band Monolithic Microwave Integrated Circuit (MMIC) six-port junction circuits realized in GaAs PHEMT technology at TriQuint Texas Foundry are presented in this paper. Comparative results of simulated and measured S parameters are shown for both designs. The proposed MMIC six-port circuit is used to realize the QPSK demodulator of a Ka band direct conversion receiver.
