Experiment 5: Power Splitters using strip-line circuits
Aim: To simulate the microwave performance of several microstrip circuit power splitters using Puff software (free download from http://www.qsl.net/yo4hfu/PUFF.html Please see the download instruction sheet) and to become familiar with the operation of a Vector Network Analyser (VNA) to measure the scattering parameters of a four port network.
Q5.4 What is the difference in the S11 for a load impedance of 150W open circuit and a load impedance of 150W earthed? Explain your answer.
Q5.5 Sketch a 5 port microstrip divider circuit which is matched to a 50W load. Note the expected power output in dB of the loss-less divider and the impedance of the matching transformer line.
