DC3~5V Amplitude modulation Super heterodyne RF -110dBm Wireless Receiver Module

RF Wireless Receiver Module Used For: Anti-Theft Alarm Remote Control Toy Wireless Remote Control Garage Door/Roller Shutter

FeatureModel No.: 0020272Modulation method: amplitude modulation (OOK) Working voltage: DC3~5V Working current: 6mA RF sensitivity: -110dBm Working temperature: -40°C~+85°C Unit size: 25mm x 12.5mm x 5mm  Adopt crystal oscillator to stabilize receiving frequency 10 kinds of frequency for selection High sensitivity and reliable performanceFrequency: we can offer 315MHz or 433.92MHz, you can choose one.

ApplicationThe RF receiver modules are widely used for remote controls, remote control toys, anti-theft alarms, garage doors, roller shutter, road barrier, retractable doors and so on.

NoteIt is best to use the antenna of 1/4 wavelength, for antenna has a great impact on receiving effect of the module; normally using 50Ω single core cable. For frequency 315MHz, the length of antenna is about 23cm; for 433MHz, it is about 17cm. The position of antenna also affects the receiving effect of the module. When installing the antenna should be extended as much as possible and be away from the shield and the place in high pressure and interference.The receiving frequency, decoding mode and timing resister should be compatible with the transmitter.
