ISM Transceiver Module With +20dBm(100mW) Output Power

RFM300LR.png

1. General Introduction


RFM300LR module series’ design is based on the high performance CMOSTEK NextGenRFTM CMT2300 chip, It operate at 433/868MHz ISM band , The low receive sensitivity(–123dBm) coupled with +20dBm output power ensures extended range and improved link performance, High Adjacent Channel Rejection Ratio is -55dbc;High Blocking Rejection Ratio is -75dBc( @Frequency868.5MHz,DR = 3 kbps, FDEV = 10 kHz; BW=100kHz, 200kHzChannel spacing, interference with the same modulation,Blocking Rejection@+-1MHz)


2. Features


  • 143 dB maximum link budget.

  • Low RX current of 11mA.

  • +20 dBm output power

  • High Adjacent Channel Rejection Ratio is -55dbc @Frequency868.5MHz,DR = 3 kbps, FDEV = 10 kHz; BW=100kHz, 200kHz Channel spacing

  • High Blocking Ratio Rejectionis -75dBc@868.5MHz +-1MHz

  • Programmable bit rate up to 300 kbps@FSK/40 kbps@OOK

  • High sensitivity: down to -123dBm.

  • FSK, GFSK, and OOK modulation.

  • SMD Package (32x14.5X1mm)


3. Application
