Silicon Labs and Hope Microelectronics' Wireless Module Targets Green Energy

Based on Silicon Labs’ EZRadioPRO® wireless radio family, Hope Microelectronics’ new RFM23B and RFM31B family of RF modules provide cost-effective, turnkey wireless networking solutions for bidirectional and one-way link applications. This solution targets applications such as smart meters, in-vehicle anti-theft alarm systems, home automation systems, HVAC control units, residential security systems, high-speed data acquisition systems and wireless toys.

The RFM23B module, based on Silicon Labs’ Si4431 transceiver, provides a bidirectional connectivity solution. It offers industry-leading RF performance with output powers of up to 13 dBm, receive sensitivity of -121 dBm and ultra-low current consumption for battery-sensitive applications. The RFM23B module supports FSK, GFSK and OOK modulations with frequency coverage over the range of 240 MHz to 960 MHz. It also features an exceptionally small footprint (16 mm x 16 mm) and is available in surface mount or through-hole configurations to support varying manufacturing requirements. The RFM31B module, based on Silicon Labs’ Si4330 receiver, is ideal for wireless networking applications that require one-way link support.

Silicon Labs EZRadioPRO® ISM Band ICs

While including all the attractive features of the EZRadio® RF transmitters, receivers and transceivers, such as high integration, low cost, flexibility, low BOM and easy design-in, these EZRadioPRO® target more sophisticated ISM band applications and offer several enhanced parameters and features including continuous frequency coverage from 240 - 960 MHz and output power up to +20 dBm. Also included are built-in features such as wake-up timer, low battery detector, transmit and receive data FIFOs, power-on reset circuit and general-purpose digital I/Os.

Hope Microelectronics RF Modules

The new Hope RF modules are designed to provide versatile, high-performance and cost-competitive wireless networking solutions for OEMs and ODMs worldwide. The RFM23B and RFM31B modules are certified for operation in the US to FCC Part 90 at 915 MHz, and in Europe to ETSI 300220. The availability of pre-certified modules helps developers streamline their certification process and accelerates time to market.
