PRODUCT OVERVIEW
This bandpass filter is designed for the 169 MHz ISM band, the frequency allocation used by Wireless M-Bus mode N (EN 13757-4) and Wize, the long-range smart metering standard deployed across millions of gas, water, and electricity meters in Europe. The 169 MHz band's low frequency gives strong building penetration and extended range compared to the more common 868 MHz wM-Bus band, making it well-suited to Advanced Metering Infrastructure (AMI), industrial wireless sensor networks, and Smart City deployments.
This filter provides excellent rejection of FM broadcast, cellular, and other out-of-band interference, protecting sensitive receiver front-ends and reducing spurious emissions on transmit. Rated to +30 dBm max input, it comfortably handles the output of external PAs used in long-range Wize/wM-Bus N-mode deployments. SMA-F connectors for direct bench and lab integration.
