ALPHA-RX433S RF Solutions

ALPHA-TX ALPHA RF MODULES ALPHA-RX FM Transmitter & Receiver Modules Available as 433 or 915MHz Transmit Range up to 300m Miniature SMT Packages Data Rate up to 256Kbps Programmable Output Power 2.2 5.4Vdc Operating Voltage Standby Current <300nA Programmable Freq Deviation SPI Interface (for Config) Clock and Reset Signal for External MCU Wakeup Timer Automatic Antenna Tuning Differential Antenna Output Low Battery Detection EMC Compliant , FCC Compliant o Operates from -45 to +85 C Transmitter 3-12 Supply Voltage Programmable Output Power Receiver Applications Standby current < 0.3uA Wireless Security Systems Wake up timer function Car Alarms PLL Design Remote Gate Controls Analog and Digital Signal Strength indicator Remote Sensing Programmable receive bandwidth (67 to 400KHz) Data Capture Sensor Reporting Introduction The Alpha Modules are extremely cost effective but high performance radio modules. Supplied in a miniature Surface mount package these modules can Transmit/Receive at upto 115Kbps at upto 300m range. Operating at 2-5V, both transmitter and receiver monitor their battery voltage and can sleep with very low standby current. The modules can wake intermittently and provide direct control outputs to a microcontroller, ideally suited to battery applications. (Especially receivers ) These Modules will suit one to one multi-node wireless links in applications including car and building security, POS and inventory tracking, remote process monitoring.
