摘要

为GPS L1/L2双频接收机设计了一种双频图像抑制混频器，扩展了传统的Weaver结构。报道了一种在正交本相信号中具有相位ermr补偿能力的正交混频器，该混频器无需校准和调谐。双手图像抑制混频器的测量显示，图像抑制比(IMRR)为64dB。

A dual-band image-reject mixer for GPS with 64dB image rejection

A dual-band image-reject mixer is designed for a GPS L1/L2 dual-band receiver with an extension of the conventional Weaver architecture. The quadrature mixer with phase ermr compensation capability in the quadrature LO signal without calibration and tuning is reported. The measurement of the dual-hand image-reject mixer demonstrated 64dB image reject ratio (IMRR).
