Description[Receiver module ] Product Model: WL101-341WL101-341 superheterodyne wireless receiver module is receiving UHF ASK demodulators support ASK and OOK modulation. The receiver module has high sensitivity (-110dBm),Low-power performance, along with high dynamic range (greater than 60dB). Module uses highly integrated chip, built front-end low-noise amplifier,Mixers, filters, frequency synthesizer circuit, etc., can maximize the signal optimization. Features1.Support ASK or OOK modulation, the receiver sensitivity of -110dBm 2.Operating frequency: 433.92 MHz, bandwidth of about 150KHz 3.mains input voltage range: 3.0V-5V Working current: Type :5.0mA (Requirement:VDD=5V) Type :6.0mA (Requirement:VDD=3V)4. Quiescent Current: 1uA5. Low power consumption 6. good selectivity and spurious radiation suppression, and easy to pass CE or Fcc international certification 7. Good local oscillator radiation suppression, multiple receiver module to work with (ie, more than single income) and will not interfere with each other, used together without affecting the receiving distance 8. multiple transmission rates, the general module for 2KHz, up to 10KHz 9. Temperature range: -40-85 C10. ultra-small size of 30.25 8.5 1 (mm)11.External antenna: 32CM single core wire, wound into a spiralPackage Included:Receiver module x 1pcsTransmitter module x 1pcsAntenna x 2pcs (Short antenna for Transmitter long antenna for Receiver.)
