Abstract :
We studied the new design theory of impedance matching circuits for SiGe BiCMOS low noise amplifier (LNA), power amplifier (PA) and TIR switch for 2.45GHz wireless LAN (IEEE 80t.llb) system. Our new matching circuits are composed of conductor-backed coplanar waveguide (CPW) meanderline resonators and impedance inverters. The EM-simulated performances of BiCMOS LNA and PA connected with input and output matching circuits are in agreement with our new design theory
