TIDC-WMBUS-169MHZ

ETSI Cat. 1 Receiver-Capable wM-Bus 169MHz RF Subsystem for Smart Gas and Water Meters

TIDC-WMBUS-169MHZ

Design files

Overview

This reference design is a very low-power, ETSI Cat. 1 receiver capable RF subsystem for wM-Bus enabled smart gas and water meters at 169 MHz. It provides market-leading blocking, selectivity, and RX sensitivity numbers for all wM-Bus N-modes as per EN13757-4:2013 and their respective variants, which were defined in Italy and France. This cost-optimized design, without SAW filter and without TCXO, uses the RF friendly DC/DC to reduce the average power consumption while keeping the highest RF performance.

Features
  • ETSI Cat. 1 receiver capable RF subsystem
  • Market-leading blocking, selectivity, and RX sensitivity subsystem for wM-Bus at 169 MHz
  • Fully compliant with the wM-Bus requirements for Italy and France (with an external PA device) at 169 MHz
  • Hhighly efficient, RF friendly DC/DC converter
  • No costly SAW filter and TCXO required

This circuit design is tested and includes test firmware, SRF7 Studio GUI configuration files and Getting Started guide.
