Abstract: In this paper the design of single side band mixers to convert C to V band signals is presented. A step by step design technique, based on harmonic balance simulations is described. The mixer devices are Schottky diodes compatible with a GaAs MESFET technology. The mixers were optimized for minimum conversion loss over the widest possible bandwidth when used as both up or downconverters in order to be used on a large number of applications. The experiments show, for both applications, a minimum conversion loss in the range of 8 to 9dB and a 3dB bandwidth larger than 6GHz. !6
