1.1 Introduction
RF and microwave engineering has innumerable applications, from radar (e.g. for air traffic
control and meteorology) through electro-heat applications (e.g. in paper manufacture and
domestic microwave ovens), to radiometric remote sensing of the environment, continuous
process measurements and non-destructive testing. The focus of the courses for which this
text was written, however, is microwave communications and so, while much of the material
that follows is entirely generic, the selection and presentation of material are conditioned by
this application.
Figure 1.1 shows a block diagram of a typical microwave communications transceiver. The
transmitter comprises an information source, a baseband signal processing unit, a modulator,
some intermediate frequency (IF) filtering and amplification, a stage of up-conversion to
the required radio frequency (RF) followed by further filtering, high power amplification
(HPA) and an antenna. The baseband signal processing typically include ... read full excerpt from Microwave Devices, Circuits and Subsystems for Communications Engineering ebook
