Abstract :
This paper presents a new design theory of impedance matching circuits for single-chip SiGe BiCMOS low noise amplifier (LNA), power amplifier (PA) and T/R switch for 5GHz-band wireless LAN (IEEE 802.11a) system. Our matching circuits are composed of conductor-backed coplanar waveguide (CPW) meanderline resonators, and impedance inverter or admittance inverter. The single-chip wireless LAN transceiver amplifier is designed by using the commercial electromagnetic (EM) and SPICE co-simulator. The prototype amplifiers are fabricated and tested.
