Abstract :
This paper presents a planar reconfigurable double stub tuner, that utilizes electrostatically activated MEMS switches. The tuner consists of a "4bit/spl times/4bit" digital capacitor bank and can match loads with real parts ranging from 5 to 108 /spl Omega/ and imaginary parts from -60 to 48 /spl Omega/ at 20 GHz. Simulated and measured results are presented.
