TRM-315-LT

TRM-315-LT TRM-418-LT TRM-433-LT WIRELESS MADE SIMPLE ® LT SERIES TRANSCEIVER MODULE DATA GUIDE DESCRIPTION The LT Series transceiver is ideal for the bi0.619" directional wireless transfer of serial data, control, or command information in the favorable 260-470MHz band. The transceiver is capable of generating +10dBm into a 50-ohm load and achieves an 0.630" RF MODULE TRM-433-LT outstanding typical sensitivity of -112dBm. Its LOT 10000 advanced synthesized architecture delivers outstanding stability and frequency accuracy, and minimizes the effects of antenna pulling. When paired, the transceivers form a reliable wireless link 0.125" that is capable of transferring data at rates of up to 10,000bps over distances of up to 3,000 feet. Applications operating over shorter distances or at Figure 1: Package Dimensions lower data rates will also benefit from increased link reliability and superior noise immunity. Housed in a tiny reflow-compatible SMD package, the transceiver requires no external RF components (except an antenna), which greatly simplifies integration and lowers assembly costs. FEATURES Long range Low cost PLL-synthesized architecture Direct serial interface Data rates to 10,000bps No external RF components required Low power consumption Compact surface-mount package Wide temperature range RSSI and power-down functions No production tuning Easy to use APPLICATIONS INCLUDE 2-Way Remote Control Keyless Entry Garage / Gate Openers Lighting Control Medical Monitoring / Call Systems Remote Industrial Monitoring Periodic Data Transfer Home / Industrial Automation Fire / Security Alarms / Access Control Remote Status / Position Sensing Long-Range RFID Wire Elimination ORDERING INFORMATION PART # DESCRIPTION TRM-315-LT Transceiver 315MHz TRM-418-LT Transceiver 418MHz TRM-433-LT Transceiver 433MHz EVAL-***-LT Basic Evaluation Kit *** = Frequency Transceivers are supplied in tubes of 33 pcs.
