RF Transceivers

Radio frequency (RF) transceivers are electronic devices that can both transmit and receive radio frequency
What is an RF Transceiver?
RF transceivers transfer information wirelessly between two devices. RF transceivers includes both a transmitter and a receiver RF transceivers convert voice, video and data into a radio frequency for applications like satellite communication, mobile phones, radio and television signal.
RF Transceivers convert IF (intermediate frequency) frequency (intermediate frequency) to RF frequency and vice versa.
The main feature of the RF module is an embedded system to communicate with another device wirelessly. In an RF transceiver, the transmitter and receiver will share common circuitry. An electronic switch permits the RF transmitter and receiver to be joined to the same antenna and stops the output of the transmitter from damaging the receiver.
Transceivers are categorised by how the receiver and transmitter communication channel is managed. This can be full duplex or half duplex communication access.
What is the difference between duplex and half duplex?
This refers to the type of transmission of the data
Examples:
A telephone is full duplex as both parties are able to talk at once
A walkie talkie is half duplex as only one party can transmit at a time
How to choose the right RF transceivers
There are many types of RF transceiver around so your choice will depend on your desired application and chosen devices. Considerations when choosing a transceiver include everything from output power and supply voltage to frequency range, data rate and packaging.
