Abstract :
A high intercept points, broadband, cost-effective and power-efficient passive reflection FET double balanced mixer (DBM) is reported. This paper is based on novel approach that gives intercept points (IP3) in excess of 42dB in and conversion loss less than 9.5 dB with the LO power typically 17dBm throughout the frequency bands (RF: 600-2500MHz, LO: 550-2300MHz, IF: 50-200MHz). The 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
