摘要

描述了用于蜂窝CDMA/AMPS应用的BiCMOS LNA和混频器。由于采用了低阻抗低频输入终端，该电路具有非常高的线性度。该LNA在高增益高线性模式下实现+12.2 dBm IIP3, 16.3 dB增益和1.5 dB NF，电流为7.7 mA。该混频器在CDMA模式下实现+14.7 dBm IIP3, 10.9 dB转换功率增益和6.7 dB SSB NF，电流为8.4 mA。

Highly linear SiGe BiCMOS LNA and mixer for cellular CDMA/AMPS applications

BiCMOS LNA and mixer designed for cellular CDMA/AMPS applications are described. The circuits exhibit very high linearity thanks to low-impedance low-frequency input terminations. The LNA achieves +12.2 dBm IIP3, 16.3 dB gain and 1.5 dB NF with 7.7 mA current in the high-gain high-linearity mode. The mixer achieves +14.7 dBm IIP3, 10.9 dB conversion power gain and 6.7 dB SSB NF with 8.4 mA current in the CDMA mode.
