Linearity is a key specification in modern, digitally modulated cellular communications systems. Linearity usually comes at the price of high power consumption, however. To "cheat" that tradeoff, a technique has been demonstrated for a CMOS-based mixer developed for wireless communications in the 5.2-GHz band to achieve both high linearity and low power consumption. The mixer operates with an IF of 200 MHz and consumes a mere 6 mW of power. To learn more, click here.
