Abstract :
In this paper, a concurrent dual-band mixer with on-wafer baluns for multi-standard applications, such as WLAN, WiMAX, is presented. The operation frequency bands of this dual-band mixer are 2.4 GHz and 5 GHz, respectively. On-chip baluns are designed to transfer single-ended RF and LO signals into differential signals for the presented mixer. A topology of LC series-parallel resonance is used to arrive at dual-band characteristics. The simulated conversion gain is 5.5 dB and 5.8 dB, respectively. The 1 dB compression point, referred to input, is -14 dBm and the IIP3 is -3.5 dBm at 2.4 GHz. The RF return-loss at both bands is well below -10 dB. The isolations between three ports are all less than -60 dB. The double-side band noise factor, NFdsb, is about 10 dB. The total DC power consumption is 6.705 mW.
