Abstract

RF switching blocks play a key role in multi-user broadcast systems. This work investigates the design of a monolithic switch-matrix for dual-user digital-satellite applications in silicon bipolar technology. The circuit performs a 29-dB isolation between the two output channels and an output 1-dB compression point of +5 dBm. The good overall performance, despite the monolithic approach, is due to the adopted design choices as well as to the proposed output buffer.
