A tunable matching network for TD-SCDMA power amplifier in 0.18-μm SOI CMOS technology

Abstract

The explosion in the number of connected cellular devices and ever-increasing data bandwidth requirements have recently fueled the demand for RF Power Amplifiers (PAs) which needs PAs to cover more bands than ever before. A potential solution to this problem is by the use of Tunable Matching Networks (TMN). In this paper, we present a TMN fabricated under 0.18-μm SOI CMOS technology, focusing mainly in the impedance coverage and the power transmission. The design employs special floating body transistors as switching components to turn on and off the capacitors and the inductor array.
