RF Solutions ZETA-868-SO is a 12-pin RF Transceiver module based on advanced EZRadio® technology and the Si4455 RF transceiver chip. Operating in the 433/868 MHz ISM bands, it delivers up to +13 dBm RF output power with a sensitivity of -116 dBm at 2.4 kbps, GFSK modulation, and 0.1% BER. Designed for low IF/ISM transceiver applications, it supports frequency shift keying modulation techniques including FSK, GFSK, and OOK.
The device operates with supply voltages ranging from 1.8 to 3.6 volts DC and communicates through a serial SPI interface, allowing seamless integration with microcontrollers and embedded systems. Its small 16 x 16 x 2 mm surface-mount package facilitates compact device design.
This module is engineered for durability across wide temperature ranges from -40°C to +85°C, making it suitable for demanding industrial, automotive, and IoT applications including home automation, sensor networking, keyless entry systems, and health-monitoring devices.
Additional functionality includes 64-byte transmit and receive FIFO buffers, packet handling with preamble and sync word detection, CRC generation and checking, Manchester coding, digital RSSI, and a battery voltage sensor. Power-saving modes optimize energy consumption for battery-powered devices.
The transceiver supports multiple modulation formats for versatile wireless communication. SPI interface offers straightforward control and high-speed data exchange. Robust operation within wide voltage and temperature ranges ensures reliability.
Compact SMT form factor enables integration into space-constrained designs. Applications span industrial, laboratory, communication, and IoT systems. Manufactured with quality standards in the United Kingdom. Range capability up to 2000 meters line of sight suits long-range requirements.
Power saving and battery voltage sensing enhance energy management.
The package corresponds to RS Stock No. 903-3062. This product is ideal for engineers designing wireless transceiver modules requiring high sensitivity and flexibility in the 433/868 MHz ISM bands.
