Ultra-low loss Nona-band SMART meter RF coupler offers high electrical isolation

August 13, 2012 // By Paul Buckley
Alpha Micro Wireless has unveiled the company’s RF Savvy Series Nona-band Radio Frequency (RF) Coupler.

The patent pending device’s high 10 kV electrical isolation enables safe routing of the RF signal from the network interface card (NIC) or wireless modem to a remote external antenna via a bulk head RF connection in the meter base.

Unlike other inefficient RF coupling schemes and isolator solutions, the RF Savvy series Nona-band RF Coupler offers an ultra-low loss (less than 0.5dB @915 MHz), high electrical isolation (>10 kV) and operates universally over nine frequency bands.

RF input and output terminations are via gold plated 50 Ohm MMCX jack connectors for rugged and easy installation. The RF Coupler has been designed with a low profile (1.0 mm) generic form factor suitable for use within the enclosure of most residential and commercial/industrial electric utility meters.

The RF Savvy series Nona-band RF Coupler can be retro-fitted to most utility meters or tailored for a custom fit to specific OEM applications. Automated metering infrastructure (AMI) wireless system integrators and utility meter manufacturers can choose to retro-fit a generic, 45 mm x 45 mm x 1 mm, version of the low-profile coupler into their SMART metering applications.
