How do you use a one parameter (S11), (s1p extension) file to model a direct RF chip input in RF Budget analyzer.

I'm trying to model the TI AFE7906 and have some one port S11 input reflection files provided that describe the input behaviour of the receive ports. How can these files be entered in the RF Budget Analyer (in the "S-Parameters" element) to do this? I realize the app is looking for a two port file for it's cascade analysis but I need to model the Rx input at the end of the RF chain.

I shared one example MATLAB Script

% Load the S-parameter data from the .s1p file
S11Data = sparameters('chip_input.s1p');

% Display the S-parameter data
disp(S11Data);

% Extract frequency and S11 parameter values
freq = S11Data.Frequencies;
S11 = rfparam(S11Data, 1, 1); % S11 is the reflection coefficient at port 1

% Visualize the S11 parameter
figure;
rfplot(S11Data);
title('S11 Parameter for RF Chip Input');
xlabel('Frequency (Hz)');
ylabel('S11 (dB)');

% 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);
