Abstract

A compact, high-performance active feedback amplifier circuit is presented with more than 50 GHz bandwidth characteristic and less than ±2 ps group delay variation. InP heterogeneous bipolar transistor (HBT) technology is used to design and fabricate this amplifier circuit. Input and output return losses are better than 10 dB up to 50 GHz. The circuit also demonstrates >550 GHz gain-bandwidth product.
