摘要

双频图像抑制混频器设计用于GPS L1/L2双频接收器，这是传统编织器架构的扩展(Wu, S.和Razavi B.， ISSCC Digest, p.124-5, 1998)。本文提出了一种具有相位误差补偿能力的正交混频器，该混频器无需校准和调谐。双频阻像混频器的测量结果显示，其阻像比为64 dB。

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

The dual-band image-reject mixer is designed for a GPS L1/L2 dual-band receiver, an extension of the conventional weaver architecture (Wu, S. and Razavi B., ISSCC Digest, p.124-5, 1998). The paper presents a quadrature mixer with phase error compensation capability in the quadrature LO signal -without calibration - and tuning. The measurement of the dual-band image-rejection mixer demonstrated 64 dB image rejection ratio (IMRR).
