Save RF Blockset model created using rfsystem

Since R2021a



    filename = save_system(rfs) saves the RF Blockset™ model created using the rfsystem System object™ rfs.

    filename = save_system(rfs,newrfs) saves the model to a new file, newrfs.

    Create a fifth-order bandpass RF filter and an amplifier with the gain of 3 dB.

    f1 = rffilter('ResponseType','Bandpass','FilterOrder',5,'PassbandFrequency',[4.85 5.15]*1e9);
    a1 = amplifier('Gain',3,'NF',1.53,'OIP3',35);

    Create an rfbudget object using the elements at an input frequency of 5 GHz, an available input power of -30 dBm, and a bandwidth of 200 MHz.

    rfb = rfbudget([f1 a1],5e9,-30,200e6);

    Create an RF system using the rfbudget object and name the RF Blockset model.

    rfs = rfsystem(rfb,'ModelName','RFSystem');

    Open the RF Blockset model.


    Save and close the RF Blockset model.
