434 MHz RF Transceiver Module
This 434MHz Transmitter is an ASK Hybrid transmitter module. It uses saw resonator for frequency stability. The receiver is an ASK super heterodyne receiver with PLL synthesizer and crystal oscillator.
These are RF receivers and transmitters which work on a very simple principle i.e, the receiver outputs the data seen by the transmitter and is of the lowest cost. Its extremely small size and high range of 500ft in open space coupled with its low power consumption make it ideal for a variety of applications. These modules can be used with an encoder/decoder pair or can be directly interfaced to a microcontroller/Arduino.
