HOPERF RFM69HW-868S2R – High Power 868MHz ISM Transceiver Module
The RFM69HW-868S2R from HOPERF is a compact and efficient RF transceiver module that operates in the license-free ISM bands, including 868 MHz, making it suitable for European wireless applications. It features programmable communication parameters, high sensitivity, and narrow/wide-band support, providing the flexibility needed for complex RF applications.
With an RF output power of up to +20 dBm, and receiver sensitivity down to -120 dBm, the RFM69HW ensures robust and long-range wireless communication. Its 16-tap FIR filter, 80 dB blocking immunity, and built-in AES-128 encryption make it secure and resilient, even in harsh RF environments.
Thanks to its low RX current of 16 mA and register retention at just 100 nA, it’s also ideal for battery-powered devices. The module is suitable for a wide range of wireless applications including automated meter reading, home automation, wireless alarms, M-Bus, and industrial control systems.
