Improved Equivalent Circuit Model of GaAs FET Switch for MMIC Phase Shifter Design
Summary :
An improved equivalent circuit model of a GaAs FET switch for MMIC phase shifters is proposed that incorporates distributed lines into a lumped-constant equivalent circuit to account for distributed-line effects. The validity of the proposed model is demonstrated by applying a coupled-wave analysis to the FET switch. Comparison of the measured and the simulated phase angles of the S-parameters shows that the improved model gives much bettter accuracy than the lumped-constant model. X-band six-bit MMIC phase shifters designed using the improved model are also described.
