Abstract :
We present a double balanced resistive mixer for mobile applications using a 0.35 μm MOSFET technology. The mixer has been designed for direct conversion receivers, with RF- and IF-frequency ranges of 2-3 GHz and DC to 50 MHz, respectively. Excellent performance has been achieved. Typical values are 6 dB conversion loss, 6.5 dB noise figure, 7 dBm 1 dB power compression, 16 dBm third order intercept point, and 50 dB isolation between all ports. The mixer does not consume DC-power and the needed LO-voltage amplitude is 1 V typical. No low frequency noise was detectable down to 10 kHz. We report on the design strategy and present simulated and measured results.
