Abstract
This work presents a RF tunable impedance matching circuit. It uses a quarter-wavelength (lambda/4) transmission line loaded by a combination of switches, capacitors and inductors. With MEMS-based switches and inductors, the simulation results show that this circuit is capable of correction load reflection coefficients of up 0.5 to better than 0.38 with insertion loss between 0.74 - 2.11 dB at 2GHz.
