computeBudget

Compute results of RF budget object

Syntax

computeBudget(rfobj)

Description

computeBudget(rfobj) computes the result of an RF budget object. You can use this method only when the AutoUpdate property of the RF budget object is set to false.

Compute Results of RF Budget Object

Open Live Script

Create a modulator with output-referred second-order intercept set to 20 and available power gain set to 3.

m = modulator(OIP2=20,Gain=3,ImageReject=false,ChannelSelect=false);

Create an amplifier with 10 dB gain.

a = amplifier(Gain=10);

Create an RF budget object specifying the input frequency of the signal, power applied at cascade, and signal bandwidth.

b1 = rfbudget([m a],2.1e9,-30,100e6,AutoUpdate=false)

b1 = 
  rfbudget with properties:

               Elements: [1x2 rf.internal.rfbudget.RFElement]
         InputFrequency: 2.1 GHz
    AvailableInputPower: -30 dBm
        SignalBandwidth: 100 MHz
                 Solver: Friis      
             AutoUpdate: false

Use the computeBudget function to compute the results of an RF budget object.

computeBudget(b1)

Display the RF budget results.
