A transceiver is a combination of transmitter and receiver that transmits and receives analog or digital signals. Transceivers have a wide variety of applications ranging from low data rate wireless applications (such as mouse and keyboard) to medium data rate Bluetooth and high data rate wireless LAN 802.11 standards.  In networks, it is generally used to allow for the connection between two different types of cable connectors to send and receive signals on the Ethernet network. Transceivers are used in wireless communications to transmit and receive electromagnetic waves in free space. A transceiver comprises three main components: a transmitter, a receiver, and an LO generator or frequency synthesizer. There are typically two input signals to the transceiver front-end, a receive signal and a transmit signal. The function of the transmitter is to modulate, upconvert, and amplify signals for transmission into free space. The function of the receiver is to detect signals in the presence of noise and interference, and provide amplification, downconversion and demodulation of the detected the signal such that it can be displayed or used in a data processor.
