摘要:

利用一种新型HBT复合晶体管结构设计了一款宽带功率放大器,有效抑制了HBT的大信号Kink效应。采用微波仿真软件AWR对电路结构进行了优化和仿真,结果显示,在5~12 GHz频带内,复合晶体管结构的输出阻抗值更稳定,带宽得到有效扩展,最高增益达到11 dB,带内波动<0.5 dB,在9 GHz工作频率时,其1 dB压缩点处的输出功率为26 dBm。

关键词: 宽带匹配, Kink效应, GaAs HBT, 复合晶体管

Abstract:

A novel broadband power amplifier is designed using a composite transistor consisting of an inverted transistor parallel-connected to a standard RF power transistor to alleviate the Kink phenomenon of GaAs HBT.Simulation and optimization results based on AWR soft show that the novel composite transistor can get a stable output impedance Zout within 5~12 GHz frequency range with a wideband amplifier's peak gain of 11 dB and a ripple in band less than 0.5 dB,and its P1dB is 26 dBm at 9 GHz operation frequency.

Key words: matching;Kink phenomenon;GaAs HBT;composite transistor
