摘要：

Alowpower dual band fully integrated receiver incorporating IEEE 802.11a/b/g/n WLAN standards was manufactured using 0.13 mu m CMOS technology. In this letter, the proposed hybrid mixer, which uses both double- and direct-conversion architecture, operates in the 5 GHz band in order to eliminate the need for high LO frequency generators. This hybrid mixer is a small low power device that shares a 2.4 GHz LNA inductor with the first 5G band mixer. The receiver is operated with a single-ended 1.2 V supply demanding only 77mA at the 2.4 GHz and 90 mA at the 5 GHz bands. The error vector magnitude is 3.4%/ 3.1% at the 2.4 GHz/5 GHz bands, respectively.
