What is the least weight of the RF receiver and transmitter module?

• The “RF module” comprises of “RF Transmitter” and an “RF Receiver”. The transmitter/receiver (Tx/Rx) pair operates at a frequency of “434 MHz”. An RF transmitter receives serial data and transmits it wirelessly through RF through its antenna.The transmission occurs at the rate of 1Kbps – 10Kbps.The transmitted data is received by an RF receiver operating at the same frequency as that of the transmitter.

• The RF module is often used alongwith a pair of encoder/decoder. The encoder is used for encoding parallel data for transmission feed while reception is decoded by a decoder.

OR

• An RF module (radio frequency module) is a usually small electronic device used to transmit and/or receive radio signals between two devices.

• In an embedded system it is often desirable to communicate with another device wirelessly.

• This communication may be accomplished through radio frequency communication.
