Abstract :
A broadband single-ended MESFET mixer is described that utilizes a new mixing mode in a dual-gate MESFET. It has reduced local oscillator (LO) penetration in comparison to the usual mixing mode of dual-gate mixers described in the literature. The measured LO reduction is 9 dB. This can be advantageous especially in the case of broadband upconverters, where the overlapping LO and RF bands can make suppression of the LO impossible
