Abstract :
A variety of fixed and variable gain amplifier MMICs (monolithic microwave integrated circuits) for applications up to 6 GHz are presented. The circuits are fabricated using an f/sub T/=10 GHz, f/sub max/=20 GHz, nonpolysilicon-emitter silicon bipolar process. Three amplifier topologies and their performance are reported: a fixed-gain wideband amplifier, a high-gain low-noise amplifier than can also be effectively used as a transimpedance amplifier, and a variable gain amplifier. These MMICs illustrate the capability of silicon bipolar technology to offer cost-effective solutions for microwave applications up to 6 GHz and for digital lightwave applications up to 5 Gb/s.<>
