% function Vg = Pin2Vg(P_dBm,Rin)
%
% Converts RF input power in dBm to the equivalent generator voltage in V 
% given a generator series resistance of Rin.
%
% Inputs:
%   P_dBm: Incident power [dBm]
% Outputs:
%   Vg: Generator voltage [V]

    P_W = 10.^((P_dBm-30)./10);
    Vg = sqrt(8*Rin*P_W);
