Introduction

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