RF Receiver, Transmitter, and Transceiver Finished Units

The RFD21793 is a manufacturer-designed RF receiver/transmitter/transceiver finished unit, designed to be used for several applications including antenna, data transmission, video transmission, wireless networking, and remote control applications.

Working Principle of RFD21793

The RFD21793 is designed with a layered circuit topology, consisting of a receive path, a transmit path, and a transceiver path. The receive path contains a power amplifier, a low noise amplifier (LNA), a mixer, and a bandpass filter. The transmit path contains a balanced mixer, a low noise amplifier, and a power amplifier. Both paths allow the RFD21793 to receive and transmit signals in either C or S band frequencies. The transceiver path receives and transmits signals through an oscillator, which is connected to both the receive and transmit paths. The oscillator provides the signals for both paths. The frequency of the oscillator can be tuned, allowing the RFD21793 to be used in applications where the frequency of the signal must be adjusted. The oscillator is adjustable from approximately 50 MHz to 1000 MHz.The RFD21793 also includes additional circuitry for protection from high voltage, over-current, and thermal protection. The protective circuitry ensures that the RFD21793 can be safely used in potentially hazardous environments.
