WebbDescription The Mixer block performs signal frequency translation and nonlinear amplification. For a given RF input signal, VRF = ARFcos (ωRFt) and an LO input signal VLO = AcLOcos (ωLOt), the mixer multiplies the signals at the input ports: WebbNonlinear amplification is modeled as a polynomial (with the saturation power computed automatically). It also produces additional intermodulation frequencies. Amplifier block …
Webbnonlinear relationship between input and output signals. This block includes memory effects: the output response depends on the current input signal and the input signal at previous Use this block when transmitting narrowband signals into your RF system. The Power Amplifierblock mask icons are dynamic and show the model WebbDesign Receiver in RF Budget Analyzer App. You can model the DCR with an RF chain that has the following stages: Attenuator — Prevents saturation and overload of the RF front-end by strong incoming signals that can desensitize or damage the receiver. Surface acoustic wave (SAW) filter — Performs RF band selection.
WebbUser-Defined Nonlinear Amplifier Model. Generate user-defined custom models by creating an RF Toolbox™ object in the MATLAB® workspace and importing it into an Equivalent Baseband amplifier block. Create a nonlinear amplifier with an adjustable Pin-Pout curve. Simulate intermodulation products in a two-tone test model. 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.
