Superheterodyne receiving module RXB3

Published:2011/8/9 17:35:00 Author:Vicky | Keyword: Superheterodyne receiving module | From:SeekIC

The module uses crystal frequency stabilization technology. It has relatively high frequency stability and uses SYN400R as the superheterodyne receptor. The receiving sensitiveness is high, the performance is stable, the current is low, the usage is easy, the size is small and it is cheap. The short antenna can be connected in the outside so that it is convenient to use. It can transmit direct current to the 2500BPS signal. Product specification Working voltage: DC 2.7~5.5V Transmission rate: 2~4KBPS Working mode: ASK amplitude modulation Working current: 2MA Receiving sensitiveness: -99dBm Size of appearance: 30×11×5mm Working temperature: -40℃~+85℃ Working frequency: 315 MHz;433 MHz; Output frequency stability: ±30PBM Output signal: CMOS electrical level Ranking of pins: ANT、 +5V、SHUT、DATA、GND Function of pins: ANT: antenna +5V : working power DC 5V ; SHUT: power-saving module； DATA: receiving data output VSS: ground connection
