Matching,neral it is much better to try and ensure that all circuits and subsystems have port impedances equal to some system characteristic impedance. If this is the case then the system can be assembled without worrying about internal reflections.

Microstrip,the input and output, bias lines for the d.c. supply to the transistor and d.c. blocking capacitors at the input and output to decouple the circuit. The capacitors are discrete components mounted between gaps in the microstrip lines.

Waveguides,om a source can be delivered to the desired load, and without causing interference to other systems. Waveguides have advantages over cables at high microwave and millimetre wave frequencies in terms of lower propagation loss and more simple manufacture.

Active Devices,f these units are the active devices such as diodes and transistors, and their influence on the complete circuit is generally modelled in terms of equivalent circuits for the element. The operation of the basic active devices will now be discussed, along with their equivalent circuits.
