Spring antenna is specialized for wireless data transmission. This antenna with good performance of V.S.W.R, small size design, easily installation, stable performance and good anti-shock and anti-aged compatible for Hoperf Modules.
RFM50 module series’ design is based on the high performance RF50 SoC chip, It include a CIP-51 core‘ MCU and 100mW transceiver. It operate at 433/470/868/915 MHz ISM band, comply with FCC, ETSI regulation.
The RFM69 series is a highly integrated RF transceiver capable of operation over a wide frequency range, including the 433, 868 and 915 MHz license-free ISM (Industry Scientific and Medical) frequency bands. Its highly integrated architecture allows for a minimum of external components whilst maintaining maximum design flexibility. All major RF communication parameters are programmable and most of them can be dynamically set. The RFM69HW offers the unique advantage of programmable narrow-band and wide- band communication modes without the need to modify external components. The RFM69HW is optimized for low power consumption while offering high RF output power and channelized operation. TrueRF? technology enables a low- cost external component count (elimination of the SAW filter) whilst still satisfying ETSI and FCC regulations.
