| 中文摘要 | 本研究利用 0.15微米砷化鎵假型高速電子移動電晶體製程實現了含有馬尚爾巴倫之 2-8 GHz吉爾伯微降頻器。由於特殊的半絕熱砷化鎵基板提供了微波被動元件低衰減的特性,這個單壓操作的假型高速電子移動電晶體吉爾伯微混頻器有寬頻的表現,其中寬頻的吉爾伯混頻器扮演了重要的寬頻差動本地震盪源產生的角色,可以提供精準的相位以及振福訊號。另一方面,由於電晶體的高轉導特性,這個混頻器有不錯的轉換增益從 13-11 dB還有寬頻的表現從 2 GHz到 8 GHz。而這個成品的總電流消耗為 3.1毫安培在 5.5伏特的操作之下。 |
| 英文摘要 | A 2-8 GHz down-conversion Gilbert micromixer with planar Marchand balun is demonstrated in this paper using 0.15 μm GaAs pseudomorphic high-electron mobility transistors (pHEMT) technology. Thanks to the semi-insulating GaAs substrate, microwave passive components have a low-loss feature. A single-voltage-supply pHEMT Gilbert micromixer is demonstrated with broadband performance while a broadband Marchand balun is employed to generate wideband differential LO signals with accurate phase and amplitude. Moreover, due to the high transconductance, the mixer has conversion gain from 13-11 dB and wideband performance from 2 GHz to 8 GHz. The current consumption of this work is 3.1 mA at a 5.5 V supply voltage. |
