Function
-
An RF transceiver is used to modulate and demodulate transmission of RF signals. The RF transmitter carries the RF signal, and the RF receiver receives it. The transmitter uses a data modulator device, a frequency and a power amplifier to produce RF signals for transmission. The RF receiver has its own frequency converter to convert and receive demodulated RF signals.
