Matching,mpedance other than . will cause reflections of power to be set up. Any devices such as diodes, transistors, mixers and antennas are almost certain to have an impedance different from .. With devices, circuits or subsystems having different impedances connected into a system, a series of reflections

Matrix Representation of Circuits and Signal Flow Graphs,omponents. More and more, computer analysis is being used to simulate the behaviour of microwave circuits, and this can provide very accurate results. The disadvantage of computer analysis is that it gives very little insight into the physical behaviour of the circuit.

Active Devices,h as detection, mixing, power generation and signal control such as electronically controllable attenuation, phase shift and switching. At the heart of these units are the active devices such as diodes and transistors, and their influence on the complete circuit is generally modelled in terms of equ

Detectors and Mixers,which also translates the signal from one frequency to another. This frequency translation gives us the ability to simultaneously transmit different signals at different frequencies — generally called frequency division multiplexing.
