摘　　要：提出了一种用于气体频谱分析传感器的混频器优先的245 GHz次谐波接收机。该接收机具有高线性度、高带宽、低噪声系数、低功耗和高集成度的特点。该接收机由2次无源反接并联二极管对(APDP)次谐波混频器、120 GHz推推型压控振荡器-分频器链路和120 GHz功率放大器构成。采用特征频率/最大振荡频率为300 GHz/500 GHz的SiGe BiCMOS工艺进行实现。结果表明,该接收机芯片的转换增益为-16 dB,带宽为14 GHz,单边带噪声系数为19 dB,输入1 dB压缩点为0 dBm,功耗为213 mW。A mixer-first 245 GHz subharmonic receiver for gas spectroscopy sensor application had been proposed.The receiver was characterized by high linearity,wide bandwidth,low noise figure,low power,and high integration level.The receiver consisted of a 2 nd passive antiparallel diode pair(APDP)subharmonic mixer(SHM),a 120 GHz push-push VCO with 1/64 divider,and a 120 GHz power amplifier(PA).The receiver was fabricated in a SiGe∶C BiCMOS technology with fT/fmax=300 GHz/500 GHz.The results showed that the measured conversion gain was-16 dB at 245 GHz with 3-dB bandwidths of 14 GHz,the single-side band(SSB)noise figure was 19 dB,the simulated input referred 1 dB compression point was 0 dBm,and the receiver dissipated a power of 213 mW.
