Abstract :
A novel and a robust synthesis technique for designing broad-band matching network is described. Such a matching network will be designed as a band-pass filter that provides broad-band match while absorbing device parasitic within the matching network. This matching network is used in designing a broad-band class AB power amplifier with a flat large signal gain of 12 dB with ±1 dB variation at saturation and output power of 39 dBm over the band from 1.6 GHz to 2.4 GHz with 800 MHz bandwidth. The drain efficiency over 65% is achieved in this entire band of operation corresponding to 40% fractional bandwidth.
