Abstract

PURPOSE:To attain a microwave band mixer having an excellent characteristic of low noise and an advantage of a drain mixer with high converting efficiency by inserting an image signal blocking filter between a drain terminal and a local oscillation input terminal. CONSTITUTION:A block filter 13 for image signal having a frequency fm (fm=2 f1-fs) is provided at a location between a drain terminal 6 and a local oscillation signal input terminal where the impedance to an image signal viewed from the drain terminal is short-circuited, where f1 is a frequency of a local oscillation signal and fs is a frequency of a high frequency signal. Thus, the mixer is operated for image recovery and the image signal is converted again into an intermediate frequency signal effectively, then the conversion efficiency is improved and low noise exponent is realized.
