RF Module

High sensibility, good performance and perfect parameter, integral screen shell and embedded filter are used for better interference immunity in harsh environment. This series of modules are specially designed for field wireless communication where the professional requires the stability as the key. The modules have FCC, CE and RoHS certificates and been integrated in many export-oriented products. ============================================================== Application: Series HAC-LEN data RF module is suitable for: Matching for the exports; Communication of army and police; Data transmission system for railway, electricity and oil field; Industrial remote controlling and remote testing, automatic data collecting system ============================================================== Features: 1. The transmission power is 500mw or 800mw. 2. Frequency range 868/915MHz. 3. The highest receiving sensitivity is -118dBm@1200bps. 4. High anti-interference and low BER (Bit Error Rate). Based on the GFSK modulation mode, the high-efficiency forward error correction channel encoding technology is used to enhance datas resistance to both burst interference and random interference ,meanwhile the actual bit error rate can be achieved 10-5～10-6 when channel bit error rate is 10-2. 5. Long transmission distance Within the range of visibility, the max reliable transmission distance is 2Km (BER=10-3/1200bps) when the antenna height is greater than 2m, the reliable transmission distance is more than 1Km (BER=10-3/9600bps). 5. Use for industry/army Because of adopting the high quality component and high reliable TCXO crystal, the temperature can achieve -35°C to +80°C ( industry grade). 6 Transparent data transmission Transparent data interface is offered to suit any standard user protocol. Any false data generated in the air can be filtrated automatically (What has been received is exactly what has been transmitted). 7 Multi-channel The standard HAC-LEN series configuration provides 8 channels. If the user needs, it can be extended to 16/32 channels, meeting the multiple communication combination mode of the user. 8 Three kinds of interface modes(TTL、RS-232、RS-485) RS232, RS485 interface diversion chip, DB9 standard interface connector and special power connector are used. 9 Large data buffer zone Interface baud rate is 1200/2400/4800/9600bps with format of 8N1/8E1 and user can define it by itself. It can transmit unlimited data when Interface baud rate is not bigger than air effective baud rate band. 10 Intelligent data control and the user does not need to prepare excessive programs. Even for semi duplex communication, the user does not need to prepare excessive programs, only receiving/transmitting the data from the interface. HAC-LEN series will automatically complete the other operations, such as transmission/receiving conversion in the air, controlling, etc. 11 HAC-LEN has two lights, which can indicate the power source and the data transmission and receiving. ============================================================== Specification: Frequency range: 868.050-869.926MHz 912.200~916.690MHz Frequency reliable : ≤±3ppm Modulation mode: GFSK Transmission power: 27dBm (500mw) Receiving sensitivity: -113～-118dBm( -115dBm@9600bps/SINAD 12dB, -120dBm@1200bps/SINAD12dB) Interface velocity : 1200～38400bps ( different according to the type) Format of the interface data: 8E1/8N1 Working temperature: -35°C～80°C (industry grade) Power: +4.75V~+5.5V (500mw) +7.2V~+9V (800mw) Transmitting current: ≤450mA (500mw) ≤500mA (800mw) Receiving current: ≤50mA Working humidity: 10%~90% relative humidity without condensation Dimension : 78 mm*6 mm*5mm
