Product Description
HopeRF RFM68W-868-S2 is a compact and cost-effective RF module transmitter designed for 868 MHz ISM band communications. With support for both Frequency Shift Keying (FSK) and On-Off Keying (OOK) modulation techniques, it provides flexible transmission options suitable for various industrial and commercial wireless applications.
Operating at a carrier frequency range from 860 to 870 MHz, this module delivers a maximum output power of +10 dBm, enabling reliable short-range communication. It supports data rates up to 100 kbps, which fulfills the needs of many telemetry and control systems.
The module comes with a surface mount type form factor and an interface via Two-Wire Interface (TWI), facilitating seamless integration with microcontrollers and embedded systems. It operates within a supply voltage range of 1.8V to 3.6V and can withstand operating temperatures from -20 to 70 degrees Celsius, making it suitable for diverse environmental conditions.
The device features fractional-N PLL with a typical step size of 1.5 kHz and frequency agility that supports Frequency Hopping Spread Spectrum (FHSS) modulation for interference mitigation and secure transmissions. Its compact size, 14.5 mm width by 15 mm length by 1.7 mm height, ensures suitability in space-constrained applications.
Typical uses include remote keyless entry systems (RKE), remote control and security applications, and local communication modules for Internet of Things (IoT) deployments. This transmitter module offers low bill of materials (BOM) cost while delivering sophisticated features.
The module supports both FSK and OOK modulation formats for versatile data transmission. Maximum RF output power is +10 dBm for effective short-range communication. Surface mount design with TWI interface simplifies integration into circuits.
Compact dimensions enable convenient installation in small devices. Operates reliably from -20 to 70 °C across varying environments. Carrier frequency range is from 860 to 870 MHz covering ISM band operation. Low supply voltage from 1.8V to 3.6V minimizes power consumption.
Supports high data rates up to 100 kbps suitable for telemetry. Frequency agility with fractional-N PLL allows FHSS modulation. Ideal for use in IoT, remote keyless entry, security and control systems.
