Abstract :
A low-loss, low-distortion continuously tunable matching network, is demonstrated at 2 GHz in a silicon-on-glass varactor IC technology. The tuner uses an optimized varactor configuration to minimize distortion, and exhibits less than 0.5 dB loss and IM3<-50 dBc at 27 dBm output power, and tunes with a VSWR>250:1 to 1:1.
