The ADF7021 narrowband transceiver from Analog Devices operates in multiple frequency bands between 80 and 940MHz. It achieves receiver sensitivity of -123 dBm at 1kb/s and has a T/R switch, VCO tank, RF/IF filters, and fully automatic AFC and AGC. The IC complies with European ETSI-300-220; North American FCC Parts 15, 90, 95; and Japan ARIB STD-T67 regulatory standards.
Because of its sensitivity and good interference blocking, the ADF7021 is suited to high-reliability and maximum-range applications. These include wireless automatic meter reading (AMR), wireless home automation, industrial control and monitoring, and remote security.
