Abstract
A high intercept points, broadband, cost-effective, and power-efficient double balanced mixer (DBM) is reported. The passive FET mixer using novel approach demonstrated in this work can operate with low noise figure and high dynamic ranges without the need of excessively high drive level, and gives input intercept points (HP3) in excess of 43 dBm and conversion loss 9 dB with the LO power typically lSdBni for the frequency band (RF: 800-2400 MHZ, LO: 750-2200 MHz, IF: 50-200 MHz). The measured interport isolation is better than 30 dB for broadband applications, and the circuit topology is not limited to these frequencies, and can be easily extended for present and later generation of communication systems.
