Abstract :
Microwave balanced diode and GaAs MESFET mixers have been designed and simulated using a computer-aided procedure. Microstrip circuit implementations of these mixers have been built. Two types of microstrip couplers, branch-line and rat-race in ring form were implemented in the design of the diode mixers. Practical measurements agree well with simulated computer results
