Abstract :
The analysis and optimizing design for PHEMT drain mixer circuit in Ka-band is given in this paper. The nonlinear equivalent circuit and its parameters are simulated and obtained from the small signal S-parameter and the DC measurements of the PHEMT device. The drain mixer circuit is designed with optimization, making use of the harmonic balance method and the conversion matrices method. The result shows that the mixer has conversion gain 4 dB at RF 27.4 GHz and LO 33.4 GHz/10 dBm.
