RF Receiver Module ASK (OOK) /315/433.92MHz RFRM4302-RXN3S RF Receiver Module General Description • The RFRM4302-RXN3S is a miniature receiver module that receives On-off keyed (OOK) modulation signal and demodulated to digital signal for the next decoder stage. Local oscillator is made of PLL structure. The result is excellent performance in a simple to use, with a very low external component count. • The RFRM4302-RXN3S is designed specifically for remote-control and wireless security receiver operating at 315MHz/433.92MHz in the USA under FCC part 15 regulation. Features • ASK (OOK) Super Heterodyne Receiver Module for 315MHZ/433.92MHZ • Low Power Consumption and Standby Current: 5uA (typ.) • Excellent Sensitivity for both 315MHz and 433.92MHz • 13.226 MHz Crystal Oscillator for 433.92MHz and 9.509MHz Crystal Oscillator for 315MHz • Can get different RF frequency with Minor Component Change on the same board. • Build-in LNA, AGC, RSSI, PLL, VCO, PFD, IF Ceramic Filter and PD • Few external components and Low cost • RoHS Compliance Applications • Remote Control Systems • Video Sender Remote Controller • Car Alarm Systems • Home Security Systems • Automation Systems • Remote keyless Entry System • Garage door openers TAITRON COMPONENTS INCORPORATED www.taitroncomponents.com Tel: (800)-TAITRON Fax: (800)-TAITFAX (800)-824-8766 (800)-824-8329 (661)-257-6060 (661)-257-6415 Rev.
