2～16GHz Distributed Broadband Amplifier

摘要

A distributed configuration for a broadband amplifier is presented in this paper. broadband amplifier has been realized by 0.2μm GaAs process in ADS2011 simulator. amplifier should be designed to trade-off noise figure, gain, bandwidth, and return loss. The aims of design are to provide less ripple variation of power gain in working frequency band. The design using distributed amplifiers, and this amplifier exhibits high performance including input/output Voltage Standing Wave Ratio is lower than 2.0 over 2～16GHz. the ripple variation of power gain is less than ±0.6dB, the typical power gain is more than 12.8dB, noise figure is less than 3.4dB.
