Transceiver design

A transceiver is a system that contains both a transmitter and a receiver. The transmitter from one transceiver sends a signal through space to the receiver of a second transceiver. After receiving the signal, the transmitter from the second transceiver sends a signal back to the receiver of the first transceiver, completing a two-way communications data link system, as shown in Figure 1.1. There are many factors to consider when designing a two-way communications link. The first one is to determine the operating frequency. Several consideration need to be evaluated to select the frequency that is going to be used.
