摘要

提出了一种带宽为2ghz、中心频率调谐为10 ~ 40ghz的带通反射型n路滤波器（RMNF）。该设计包括一个宽带混合耦合器，n路反射器，包括四相无源混频器，端接三阶同相和正交相有源基带负载，以及宽带时钟生成网络。反射器实现带内开路和带外匹配终端，在反射模式下提供带通响应。该滤波器采用GlobalFoundries 45纳米RFSOI工艺制造。在10至40 GHz调谐范围内，该带通滤波器具有18 dB/倍频滚降、3.6-6.3 dB插入损耗、40 - 20 dB带外抑制、6-12 dB噪声系数、+22 - +12 dBm带外输入参考三阶截距点和130-332 mW的功耗。

A 10 to 40 GHz Reflection-Mode N-Path Filter

A bandpass reflection-mode N-path filter (RMNF) with 2-GHz bandwidth and 10 to 40 GHz center-frequency tuning is presented. The design includes a broadband hybrid coupler, N-path reflectors, comprising four-phase passive mixers terminated with third-order in-phase and quadrature-phase active baseband loads, and a broadband clock-generation network. The reflectors realize an in-band open circuit and an out-of-band matched termination, providing a bandpass response in reflection mode. The filter is fabricated in the GlobalFoundries 45-nm RFSOI process. Across the 10 to 40 GHz tuning range, the bandpass filter has 18 dB/octave roll-off, 3.6–6.3 dB insertion loss, 40–20 dB out-of-band rejection, 6–12 dB noise figure, +22–+12 dBm out-of-band input-referred third-order intercept point, and 130–332 mW of power consumption.
