Reconfigurable and cost-effective FET mixer

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 typical measured input intercept points (IIP₃) and conversion loss is 38 dBm and 8.5 dB with the LO power typically 15 dBm for the frequency bands (RF: 700-2300 MHz, LO: 650-2100 MHz, IF: 50-200 MHz).
