摘要: 本文介紹一種結(jié)構(gòu)新穎、性能優(yōu)良的8mm波段和頻上變頻器。變頻器的變頻損耗為2.9dB;1dB壓縮點(diǎn)輸出功率1.34mW;和頻信號(hào)小于1mW范圍內(nèi),變頻器具有極好的線性;和頻信號(hào)比雜散組合頻率譜線強(qiáng)30dB以上;各端口隔離度均大于40dB。

Abstract: 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. -
