Abstract
GaAs f.e.t. mixer operation is investigated at 6 GHz when the intermediate frequency is around 1 GHz. A 3 dB improvement in noise figure is measured, compared with 30 MHz i.f. operation. Other characteristics, such as conversion gain and dynamic range, are similar. Broadband operation is also investigated. With 0.5 ¿m gate device, on s.s.b. noise figure of 5.6 dB is achieved with a conversion gain of 10 dB.
