Narrow Band Multi-Channel RF Transceiver Module

Product Description

The RC1240, RC1280 and RC1290 RF Transceiver Modules are compact surface-mounted

high performance modules for 25 kHz narrow band FSK operation with embedded protocol.

The modules are completely shielded and pre-certified for operation under the European and

US radio regulations for license-free use. When used with quarter-wave antennas a line-of-

sight range of 2-4 km can be achieved at 433 MHz.

Applications

• OEM equipment

• Radio modems

• Alarm and security systems

• Point-of-sales terminals

• Bar code scanners

• Telemetry stations

• Fleet management

Features

• Smallest in the world (12.7 x 25.4 x 3.5 mm)

• 25 kHz narrow band multi-channel operation

• Very low current consumption, 3nA OFF mode

• Embedded RC232™ protocol

• Addressing and Error check

• 128 byte data buffer

• Simple UART interface for easy RS232/422/485 wire replacement

• Compact shielded module for SMD mounting

• No external components

• No configuration required for single-channel use

• Easy to use data interface, 3/5 V tolerant I/O

• Wide supply voltage range, 2.8 – 5.5 V

• Conforms with EU R&TTE directive (EN 300 220, EN 301 489, EN 60950) for 25kHz

• Conforms with FCC CFR 47 part 15
