Abstract :
A new W-band balanced monolithic HFET doubler has been designed, fabricated and characterized. The doubler was simulated by linear analysis and a harmonic balance method. A new large signal HFET model was applied for the analysis of the balanced HFET doubler. The experimental investigation confirm the results of the harmonic-balance simulations. Experimentally an output power of ¿5 dBm at 90 GHz and a conversion loss of approximately 15-18 dB (2-3% efficiency) at 88-96 GHz with an input power of 10 dBm.
