A RF-MEMS Based Tunable Matching Network for 2.45-GHz Discrete-Resizing CMOS Power Amplifiers
Abstract
This paper deals with the design and experimental validation of a tunable matching network for discrete-resizing CMOS power amplifiers operating at 2.45 GHz (i.e. in the WiFi frequency band). The network is based on a two stages ladder configuration and exploits high-Q MEMS capacitors to achieve the impedance tuning. Furthermore, since these capacitors can be programmed through a 3-wires serial interface, a fully digital control of the transformed impedance is achieved.
