WebbCMOS RF Power Amplifiers: Nonlinear, Linear, Linearized David Su Atheros Communications Sunnyvale, California. 2of41 IEEE Local Chapter Nov 2002 Outline 1. • Introduction • Nonlinear Power Amplification • Linear Power Amplification ... Efficient switched-mode amplifier Create an RF Toolbox amplifier object with the default property values. Then, generate the Pin-Pout data (in watts) for the amplifier by dividing the square of the input and output voltage vectors by the reference impedance of the amplifier. Use the Pin-Pout data to specify the nonlinearity of the amplifier object. For … Visa mer Use MATLAB commands to create a vector of polynomial coefficients that define the desired Vin-Vout relationship. A MATLAB convention is to store nth order polynomial coefficients in a row vector of length n+1 with the nth … Visa mer Define the S21 parameter of the amplifier at the frequency point for which you specified the power data. The S21 network parameter must be … Visa mer To increase the source power from 7dBm to 8 dBm from a MATLAB script, first get the handle to the current Simulink® model workspace. Then set the appropriate workspace variable … Visa mer The following figure shows the test harness for your new amplifier. The input signal consists of the sum of two tones, one 10kHz below the center frequency, and one 10kHz above it. The spectrum scope shows the … Visa mer
