Extract the S-parameters of a Device Under Test (DUT) using the deembedsparams function.
Write out the data in rfckt objects you create in the MATLAB® workspace into an industry-standard data file: Touchstone®. You can use these files in third-party tools.
A how to separate the S-parameters of two identical, passive, symmetric probes connected in a cascade.
Design a broadband matching network between a resistive source and inductive load using optimization with direct search methods.
Use the RF Toolbox to determine the input and output matching networks that maximize power delivered to a 50-Ohm load and system. Designing input and output matching networks is an important
Verify the design of input and output matching networks for a Low Noise Amplifier (LNA) by plotting its gain and noise.
Calculate the cascaded gain, noise figure, and 3rd order intercept (IP3) of a chain of RF stages. Each stage is represented by a frequency independent "black box", specified with it's own
Create and use RF Toolbox™ circuit objects. In this example, you create three circuit (rfckt) objects: two transmission lines and an amplifier. You visualize the amplifier data using RF
Compute the time-domain response of a simple bandpass filter:
Use RF Toolbox™ to model a differential high-speed backplane channel using rational functions. This type of model is useful to signal integrity engineers, whose goal is to reliably connect
Use RF Toolbox™ functions to calculate the TDR (Time-Domain Reflectometry) and TDT (Time-Domain Transmission) of a differential high-speed backplane channel.
Use Simulink® to simulate a differential high-speed backplane channel. The example first reads a Touchstone® data file that contains single-ended 4-port S-parameters for a differential
Use RF Toolbox™ to import N-port S-parameters representing high-speed backplane channels, and converts 16-port S-parameters to 4-port S-parameters to model the channels and the
Use the 'NPoles' parameter to improve the quality of the output of rationalfit. By default, the rationalfit function uses 48 or fewer poles to find the rational function that best matches the
Use the 'Weight' parameter to improve the quality of the output of rationalfit. By default, the rationalfit function minimizes the absolute error between the data and the rational
