摘要
本文介绍了一种密封式匹配负载,以及将它置于冷、热态作为一种噪声源在低噪声FET放大器及毫米波混频器测试中的应用。叙述了一种新的毫米波混频器微波参数测试方法,特别适用于开放式结构的毫米波接收前端。
A sealed coaxial matched load at hot or cold condition used in the measurement of low-noise FET amplifier and millimeter wave mixer is described. A new measuring method for millimeter wave mixer is presented, which is suitable for measuring millimeter wave receiver of open waveguide.
