Abstract :
The design of a direct quadrupler of a 5 GHz input signal to 20 GHz, using a single 0.3 ¿m MESFET, is described. Aminimum conversion loss of 6.5 dB has been measured, including about 2 dB of insertion loss of the MIC output filter. Due to the isolation provided by the FET, the input and output matching circuits can be designed independently. No idler circuits for the 2nd and 3rd harmonics are required.
