A 15-GHz AlGaAs/GaAs HBT limiting amplifier with low phase deviation

The design and performance of a 15-GHz AlGaAs/GaAs HBT limiting amplifier is presented. The key feature of the circuit design is a differential configuration with an emitter peaking technique to realize a low phase deviation and wide frequency band. A high-frequency operation of 15 GHz with a gain of 25 dB and a low phase shift deviation of 3 degrees over a 15-dB input dynamic range has been achieved.<<ETX>>
