Abstract :
The design and performance of single-device and balanced versions of (M)MIC (microwave and monolithic microwave integrated circuit) GaAs FET frequency doublers from 18 GHz to 36 GHz, fabricated in purely CPW techniques, are presented. Coplanar discontinuities which are usually neglected are taken into consideration in the analysis and design. Spiral inductors and their associated parasitic capacitances are used for impedance matching and phase shifting purposes. Simulation and measurement results are in good agreement. The investigated doublers have a minimum conversion loss of 7 dB.<>
