Analog Devices is offering a couple of RF transceivers aimed at smart metering and home and building automation applications. 

It is anticipated that RF links will be used for the secure transmission of energy usage and control information over short distances within the home. Wide area data links will be used communicating with utility computers over wireless networks.

The ADF7022 RF transceiver and ADF7023 RF transceiver operate on the short-range ISM-band (industrial, science and medical) for remote data measurement.  

The ADF7022 RF transceiver includes an integrated communications processor to support the ribosome protocol, which will be used to control remotely home systems, such as garage doors and heating systems.

The ADF7023 short-range RF transceiver is a low-power, low-IF transceiver designed for operation in the license-free ISM bands at 433MHz, 868MHz and 915MHz.

The ADF7023 includes enhanced baseband features and offers a low transmit-and-receive current, as well as data rates in 2FSK/GFSK up to 250kbit/s.

It operates with a power supply range of 1.8 V to 3.6 V and has lower power consumption in both transmit and receive modes, enabling longer battery life. Other features integrated on-chip include an extremely low-power, 8-bit RISC communications processor; patent-pending, fully-integrated image rejection scheme; VCO (voltage controlled oscillator); Fractional-N PLL (phase locked loop); 10-bit ADC (analogue-to-digital converter); digital RSSI (received signal strength indication); temperature sensors; AFC (automatic frequency control) loop; and battery voltage monitor.
