computeBudget
Compute results of RF budget object
Syntax
Description
computeBudget(
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 rfobj
)false
.
Examples
Compute Results of RF Budget Object
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.

Input Arguments
rfobj
— RF budget object
rfbudget
object
RF budget object, specified as a rfbudget
object.
Algorithms
S21 = 0
If S21 of an element is zero, you make the following modifications to that element:
S21 = 0 and S11 = -1
S21 = 0 and S22 = -1
S21 = 0, S22 = -1, and S = -1
S21 = 0
Version History
Introduced in R2017a
