433.92MHz ultra Low-power OOK Receiver Module is a compact, ultra-low-power OOK (On-Off Keying) RF receiver module operating at 433.92 MHz, designed for battery-powered remote control and wireless sensor applications. The module implements a duty-cycled receive architecture that drastically reduces average current consumption while maintaining high RF sensitivity and stable operation. Duty-Cycle Receive Operation To minimize power consumption, the receiver operates in a duty-cycled mode, alternating between sleep and RX active windows. Default configuration: Sleep time: 1000 ms RX window: 20 ms Resulting average current is 75^A, ideal for long-life battery. Custom duty-cycle configurations are available on request. - Wireless security systems - Home and building automation - Automatic Measure Reading - Wireless Sensor Network Technical Characteristics Radiocontrolli s.r.l refuses any responsibility for irregular uses of the devices and for any possible lack or inaccuracy of the data and reserves the right to change in whole or in part these information without notice.

The receiver module must be powered from a regulated voltage. In proximity of the receiver module it is necessary to insert a ceramic decoupling capacitor (100nF). The ground plane must be completely encircle the entire receiver in particular the area of the Antenna connection (we recommend a minimum of 40-50mm radius). The 50ohm connection should be as short as possible. For a pcb with 1.6mm thickness, the track “50ohm connection” must be 2.5mm, this track should be separated from the GND for 2mm. On the opposite side of 50ohm connection should be a ground plane. Keep the receiver module away...
