Abstract

A CMOS doubly balanced mixer circuit is implemented with a source follower input and a cross coupled mixing quad. The circuit employs an all N-channel configuration and is suitable for high frequency applications. As a down-converter with an RF input of 2.0 GHz and a IF output of 200 MHz, the mixer demonstrates 9 dB of conversion loss with a corresponding input referred third order intercept of 0 dBm. As an up-converter with an IF input frequency of 400 MHz and an RF output of 2.4 GHz, the mixer demonstrates 14 dB of conversion loss
