Hi,
I am new to power amplifier design. I had referred RF power amplifier design by Hella & Ismail. They had said to select MOSFET sizing based on efficiency( assumed) and bias condition as a starting point and then run harmonic balance analysis to find the optimum load for the chosen size. I have attached the circuit diag. I have set the input port impedance to conjugate match the MOSFET input ( 200 + 800i) and set the variable RL as output port. Can someone tell me how to set the cadence harmonic analysis, I tried to do it and plot power contour but it displayed two dimensional sweep required.
Thanks
