摘要
本文介绍一种结构新颖、性能优良的8mm波段和频上变频器。变频器的变频损耗为2.9dB;1dB压缩点输出功率1.34mW;和频信号小于1mW范围内,变频器具有极好的线性;和频信号比杂散组合频率谱线强30dB以上;各端口隔离度均大于40dB。
A new 8 mm high-performance sum-frequency upconverter is described. Ttsconversion loss is 2.9 dB; its output power is 1.34mW at 1 dB compression point. As the power of sum-frequency signal below 1mW, the upconverter shows a very good linearity. Sum-frequency signal is 30 dB higher than stray spectrum. The isolation of each port is over 40 dB.
