Analog applications of silicon RF MOSFET circuits have received increased attention as potentially lower cost and higher integration alternatives to III-V technology. In this work, a thin-film silicon-on-sapphire (SOS) n-MOSEET based distributed amplifier is demonstrated. Impedance matching was achieved by a coplanar waveguide (CPW) on sapphire. The distributed amplifier has a bandwidth of 10 GHz and 5 dB gain. The amplifier's bandwidth is the broadest ever reported for a Si MOSFET technology.
