Smart meter RF coupler features 10kV electrical isolation and less than 0.5dB loss at 915MHz
August 13, 2012 // Julien Happich
The RF Savvy Series, patent pending, Nona-band radio frequency coupler from Alpha Micro Wireless ensures 10kV electrical isolation for the 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.
The RF Savvy series Nona-band RF coupler offers an ultra-low loss, less than 0.5dB at 915MHz 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 (1.0mm) generic form factor suitable for use within the enclosure of most residential and commercial/industrial electric utility meters.
The device 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, 45x45x1mm version of this low-profile coupler into their SMART metering applications or get a custom layout that meets their specific application needs.
