Harmonic Balance: Why?52. Harmonic Balance: How?53. First Example: a FET Amplifier Stage explored by a Parameter Simulation of the Relation between Forward Transmission S21 and Supply The 1 dB Compression Point Linear Presentation of the Transfer Characteristic for different values of the Power Supply Voltage Vdd124. Second Example: Examining this FET Amplifier Stage for a fixed Operating The Simulation Ideal an real Transfer Linear Presentation of S21 for different Input Voltage Presentation of S21 in dB (including 1 dB compression point) for differentInput voltage Rise of Harmonics for increasing Input Voltage Amplitude (linear Presentation) Rise of Harmonics for increasing Input Voltage Amolitude (presentation in dBm at 50 ) The complete Output Spectrum The IP3 Simulation of IP3 using the Transfer Simulation of IP3 using the Output Spectrum225.
