Abstract
This work presents a RF tunable impedance matching network. 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 0.3 with insertion loss between 0.74-2.11 dB at 2 GHz.Keywords
