1 RFM300H/RF FM300 SM TransceiverMo odule With +20dBm(100mW) Output Power (The purpose of this RFM300H/RFM300 spec covers mainly for the hardware and RF info of the module, For software info please refer tocmt2300 chip datasheets and demo program of HopeDuino TM Develo pment Kit) 1. eneral ntroduction RFM300H/RFM300module series design is based on the high performancecmostek NextenRF TM CMT2300 chip, toperate at 433/868/915MHz SM band, The low receive sensitivity( 120dBm) coupled with +20dBm (RFM300H)/+13dBm(RFM300) output power ensures extended range and improved link performance. RFM300H RFM Features: 140dB maximum link budget. Low RX current of 7mA. +20 dbm output +13 dbm output bit rate up to 300 High sensitivity: down to 120dBm. FSK, FSK, and OOK modulation. SMD Package (16x16X1.8mm) 3. Application: Meter Reading Wireless data collection Automobile security system Home automation and security system Tel: Fax:
