| Abstract: | A compact 5.2 GHz upconversion micromixer using the 0.35 /spl mu/m SiGe HBT technology is demonstrated. A bandpass and area-saving LC current mirror using the active inductor is incorporated to increase the conversion gain. The demonstrated upconverter has conversion gain of -3.5 dB, OP/sub 1dB/ of -10 dBm, and OIP/sub 3/ of 0 dBm. |
