Calculate the per-stage and cascade output power, gain, noise figure, SNR, and IP3 (third-order intercept) of the system. the off-diagonal elements (M u;u+1) represent the values of the admittance inverters of the network. A network comprising distributed elements should be used instead. If one uses ten sections, one gets a reasonably accurate model up to the frequency equal to the reciprocal of the propagation delay. Delay/length/phase converter. Such an approach becomes possible because the sym-metrical lumped LC-type π- or T-section is equivalent at a single fre-quency to the transmission-line sec-tion with the appropriate character-istic impedance and electrical length.
