摘要

本文设计了一种转换损耗为4.4 dB的80ghz图像恢复混频器。该图像滤波器是一个圆形高通滤波器，利用了直径减小的波导部分的截止特性。LO注入由一个te111模式带通滤波器进行。混频器噪声温度在室温下为650 K，在20 K时为280 K。下边带抑制效果优于40 dB。

Image Recovery Millimeter-Wave Mixer

This paper describes the design of an 80 GHz image recovery mixer that has a conversion loss of 4.4 dB. The image filter is a circular highpass filter using the cutoff properties of a waveguide section with reduced diameter. LO injection is preformed by a TE111-mode bandpass filter. The mixer noise temperature is 650 K at room temperature and 280 K at 20 K. The lower sideband suppression is better than 40 dB.
