% Set up an example RF budget chain
% Here, we assume the chain has an amplifier and a bandpass filter for illustration
% You should replace these with your actual RF chain components
% Example gain and noise figure for an amplifier
gain = 10; % in dB
noiseFigure = 3; % in dB
% Assume 50 ohm reference impedance for all components
Z0 = 50;
% Create RF components
amp = amplifier('Gain', gain, 'NF', noiseFigure, 'Z0', Z0);
bpf = rfbudget('Filter', 'Type', 'Bandpass', 'CenterFrequency', 1.5e9, ...
'Bandwidth', 1e8, 'Z0', Z0);
% Create the RF budget object
rfChain = rfbudget([amp bpf], freq, -30, 'SParameters', S11Data);
% Calculate the RF budget
rfAnalyze = analyze(rfChain);
% Display RF budget results
disp(rfAnalyze);
% Visualize the overall RF budget
rfbudgetplot(rfAnalyze);
