12.5kHz Channel VHF Receiver

The ENR1 is a miniature PCB mounting VHF radio data receiver. It is a narrowband 12.5KHz spacing receiver incorporating a received signal strength indicator (RSSI). It allows the simple implementation of data links at speeds up to 5kbps. ENR1 combines full screening with internal filtering to ensure EMC compliance by minimising spurious radiation and susceptibility. The module suits one-to-one and multi-node wireless links in applications including automatic meter reading (AMR), car and building security, EPOS and inventory tracking and remote industrial process monitoring.
