Abstract

A RF amplifier based on compact tunable MEMS impedance matching network was designed for sub-2GHz frequency applications. The amplifier uses a PHEMT transistor fabricated in GaAs technology while the MEMS circuits is fabricated using a dedicated UW-MEMS process. The performance of the amplifier is controlled for the PCS1900 frequency band while the gain is kept around the maximum available stable gain.
