433MHz Multichannel Radio Modem

The RCQ2-434 is a high performance wireless modem providing a reliable low cost serial data communications link that can be used for many data communications applications at an exceptionally competitive price. The modem operates in the ISM 433 MHz band. The RF modem is very simple to use and provides a wireless RS232 link with a RF data rate of up to 100 kbps. The transceivers have the functions of a complete radio modem and simply require CMOS/TTL data at the transmit input and the corresponding transceiver(s) output the same data. Preamble and CRC are automatically generated and added to the RF transmission. The RCQ2-434 can use any channel in 100 (200) KHz step. Possible applications include one-to-one and multi-node wireless links in applications including security, EPOS, wireless sensor network, industrial process monitoring and computer networking. Because of their small size and low power requirements, (the consumption in power down mode is < 2µA) this module is a ideal for use in portable, batterypowered applications such as hand-held terminals.
