New features and changes introduced in this version are
The rfckt.amplifier and rfckt.mixer objects now let you import system-level verification models of amplifiers and mixers, respectively, using data from Agilent® P2D and S2D files.
Use P2D files to specify the following data for multiple operating conditions, such as temperature and bias values:
Small-signal network parameters
Power-dependent network parameters
Noise data
Intermodulation tables
Use S2D files to specify the following data for multiple operating conditions:
Small-signal network parameters
Gain compression (1 dB)
Third-order intercept point (IP3)
Power-dependent S21 parameters
Noise data
Intermodulation tables
Use the following methods to work with operating condition data after you import a P2D or S2D file into an RF object:
setop — Use this method to set operating condition values or to list all available values.
getop — Use this method to display the selected operating condition values.
You can import an intermodulation table into an rfckt.mixer object. The object's plot method has a new option for plotting mixer spur data.
Use the new timeresp method of the rfmodel.rational object to compute the time response of an rfmodel object to a specified input signal. Use this method rather than computing impulse response with the impulse method and then convolving that response with the input signal because the timeresp method generally gives a more accurate output signal for a given input signal.
Four new plotting methods provide additional plotting options:
Use the plotyy method of the rfckt class to create a plot that contains RF circuit object data on both the left and right Y-axes.
Use the loglog method of the rfckt class to plot RF circuit object data on a log-log scale.
Use the semilogx method of the rfckt class to plot RF circuit object data using a logarithmic scale for the X-axis.
Use the semilogy method of the rfckt class to plot RF circuit object data using a logarithmic scale for the Y-axis.
Use the new gamma2z function to compute input impedance from a reflection coefficient.
Tab completion is now available in the MATLAB command window for all functions and methods. For more information on tab completion, see Completing Statements in the Command Window — Tab Completion in the MATLAB documentation.
Data tips are now available for any RF plot. For more information on data tips, see Data Cursor — Displaying Data Values Interactively in the MATLAB documentation.
Visualizing Mixer Spurs shows how to use the toolbox to perform mixer spur analysis using data from an intermodulation table and then plot the output power spectrum of the desired signal and the undesired spurs.
Modeling a High-Speed Backplane (Part 1: Measured 4-Port S-Parameters to a Rational Function Model) now uses the timeresp method to compute the time-domain response of a system characterized by measured data.
Modeling a High-Speed Backplane (Part 2: Rational Function Model to Simulink Model) now includes code that you can use to generate a Simulink model for any rfmodel.rational object.
