Microwave Diodes
13.1 Introduction
Chapter 12 encompassed different tubes to generate and amplify microwave
energy. These tasks can also be performed by semiconductor devices which
include different types of diodes and transistors. The tubes are suitable for
higher powers, higher frequencies of operation, higher operating voltages
and for higher degree of amplication linearity. On the contrary, the semi-
conductor devices have smaller size, lesser weight, low cost, higher reliabil-
ity and greater energy efciency particularly with CMOS technology. The
highly automated manufacturing processes and easy availability of their
comp
