Abstract :
A reconfigurable output matching network (OMN) for multimode multiband power amplifier (MMPA) applications has been designed and implemented using SOI CMOS RF switches and switched capacitor. The proposed reconfigurable matching network covers up to ten E-UTRA frequency bands ranging from 700 MHz to 920 MHz and presents two different impedance levels. It has been designed with four distinct RF paths, one path being dedicated to GSM/EDGE (2G/2.5G) PA applications and three paths being dedicated to UMTS/LTE (3G/4G) PA applications. The realized prototype occupies a silicon area of 1.5 mm2 in a 130 nm SOI CMOS process. A lower than 3 Ohm input impedance has been measured for different operating modes and frequency bands.
