ABSTRACT
High Frequency Circuit systematic introduction to communication
systems, particularly wireless communication systems and their basic
function of the circuit, given the qualitative and quantitative analysis
of these methods of circuit performance. The circuit includes a
transmitter and receiver in frequency selective amplifier, mixer circuits,
power amplifier, oscillation circuit, modulation and demodulation
circuits, phase locked loop circuit, automatic gain control circuits and
frequency synthesis circuit.
The basic design of this course are: the theory and practice through
teaching, so we know when the transistors operate at high working principle,
characteristics and micro-dependent equivalent circuit parameters,
frequency control circuit of the line unit composition, the basic working
principle methods, technical requirements, and some typical IC, and have
a certain theoretical level and enough of the practical skills,
communication technologies for the further study of expertise and
professional skills basis.
