摘　　要：基于0.7μm InP HBT工艺,设计了一款C波段高谐波抑制有源三倍频器MMIC。三倍频核心电路采用AB类差分级联三极管(cascode)结构,可产生丰富的奇次谐波信号,通过输出匹配网络滤出三次谐波信号并抑制其他谐波信号。输入端利用有源巴伦实现单端信号到差分信号的转换,提供较大的驱动功率同时节省面积;输出端级联缓冲放大器,提高输出功率。常温状态下,当输入驱动功率为-5 dBm时,该三倍频器在输出频率3.9~6.9 GHz范围内,输出功率大于10 dBm,偶次谐波抑制度大于33 dBc,基波抑制度大于35 dBc,五次谐波抑制度大于24 dBc。芯片供电方式为单电源+3.3 V供电,直流功耗为198 mW。Based on 0.7 μm InP HBT process,a C-band frequency tripler MMIC with high harmonic suppression was designed.The core circuit of the frequency tripler was based on the class AB differential cascaded triodes(cascode)structure which generated abundant odd harmonics. The third harmonic signal was filtered through the output matching network and the other harmonics were suppressed. The single-ended signal at input port was converted to differential signals by an active balun which could provide large driving power and saves space as well. The cascading buffer amplifier at the output port was implemented to increase output power of the tripler. Under normal temperature,when the frequency tripler is applied with power of -5 dBm,output power of more than 10 dBm,even harmonics suppression of more than 33 dBc,fundamental suppression of more than 35 dBc,5th harmonic suppression of more than 24 dBc are achieved with the output frequency range from 3.9 GHz to 6.9 GHz. The single operating voltage of this chip is 3.3 V and the DC power dissipation is 198 mW.
