摘要: This article demonstrates a high-frequency 0.35-mu m SiGe HBT subharmonic downconverter with reactive in-phase and quadrature-phase (I/Q) generators. Two reactive I/Q generators are integrated in our work to provide differential quadrature RF and LO signal. The I/Q subharmonic downconverter with single-ended LO. RF. and IF (I/Q) ports has a conversion gain of 1 a. IP(1dB) of -10 dBm. IIP(3) of 0 dBm, and IIP(2) of 21 dBm at 16.4 GHz. The magnitude and phase errors between the I and Q channels are 1.34% and 0.6 degrees. respectively. The dc power consumption of this IIQ mixer without output buffers is approximately 5 mW.
