摘要: 本論文主要在討論三顆用於W-頻段之接收機中的寬中帶頻混頻器。三個混頻器降頻的頻段分別為8.7-17.4GHz,17.4-26.1GHz跟26.1-34.8GHz。每個電路都有自己的本地震盪倍頻器。 第一部分介紹超寬頻混頻器的架構。超寬頻混頻器有RF放大級、IF放大級、LO倍頻器及雙平衡式的混頻器。LO倍頻器的部分有兩種:一個是兩倍頻器,一個是三倍頻器。 第二部分介紹三顆混頻器的佈局與結果。轉換增益為0dBm,LO-IF的隔離度8.7-17.4GHz混頻器為70dBm、17.4-26.1GHz混頻器為50dBm、26.1-34.8GHz為50dBm。
This thesis discusses three wide-IF-band mixers used for W-band receiver. The bandwidths of three down converter mixers are 8.7-17.4GHz, 17.4-26.1GHz, and 26.1-34.8GHz. All three mixers have its own LO multiplier. The first part of this thesis introduces the architecture of wide-IF-band mixer. The wide-IF-band mixer has RF amplifier, IF amplifier, LO multiplier, and double-balanced mixer. There are two kind of LO multiplier: the first one is doubler, the second one is tripler. The second part of this thesis introduces the layout and performance of three mixers. The conversion gain of mixer is 0dBm. The IF-RF isolation of 8.7-17.4GHz mixer is 70dBm, 17.4-26.1GHz mixer is 50dBm, 26.1-34.8GHz is 50dBm.
