This paper describes a reconfigurable resistive passive FET mixer co-designed with a reconfigurable VCO (voltage controlled oscillator) that acts as a LO (local oscillator), can operate with low noise figure, and high dynamic range without the need of external BALUN (balance-to-unbalance) network.

The Universal Mobile Telecommunication System (UMTS), the successor to GSM, is steadily increasing its penetration of the world’s wireless communications markets, and is likely over time to become the primary standard used by not just the current 85% wireless carriers, but by virtually all of them. Its most promising emerging enhancement, Long-Term Evolution (LTE), has moved further along in the standards-setting process and on to the path of initial deployment.
