FSK and ASK RF Modules ISM band(315,433,868 and 915MHz) ASK and FSK RF Modules are available from MENTORPORT and are professional transmitter,receiver and transceiver rf modules designed with high performance chips (transmitter, receiver and transceiver), which have all the RF functions integrated inside one chip. All that is needed for a reliable ASK or FSK system without tuning is one MCU, one crystal, one de-coupling capacitor and one external antenna. All rf modules cover the frequency range from 300MHZ to 1GHZ. The rf modules can work up to 115kbps(fsk) and can easily achieve long distance communications up to 200m.All modules are low powered and conform to both FCC and ETSI requirements and are designed to be multi-channelled.These modules all conform to European RoHs regulations. FEATURES: * ISM Band Transmitter,Receiver and Transceiver modules available. * Works from 2.2v to 5.4v * High power output: 8dbm at 433MHZ band, 6dbm at 868/915MHZ band * High receiver sensitivity: up to -109dbm * Stand by current: -0.3µA * High data rate: 256Kbps for OOK mode, 115.2Kbps for FSK mode * Wide temperature range: -40°C to 85°C * FSK modulation, very good anti-interference performance * SPI interface used for configuring all parameters, no hardware alignment is needed, frequency hopping is possible * Automatic antenna matching is built in so that the antenna is always optimized even when the RF circuit has influence from outside, such as hand held effects etc. * Programmable clock output for external MCU use reduces material costs * LVD detect circuit built in * Wake up timer built in * Bit synchronized clock output * Highly integrated, very few external components needed, low costs, no alignment needed during production For more details of these exciting new rf modules,please contact Mentorport directly either by phone or email.
