2.Descriptions The CMT2300A is an ultra-low power, high performance,OOK, FSK, MSK, GFSK and GMSK transceiver for various 213 to 960 MHz wireless applications. It is part of the CMOSTEK NextGenRFTM family, which includes a complete line of transmitters, receivers and transceivers. With the high level integration, CMT2300A simplify the external BOM. Up to +20 dBm Tx Power and -120 dBm sensitivity optimize the RF link performance. It supports multiple data packet formats and data encode/decode engines, meets the data format requirements of different applications. CMT2300A supports 64-byte Tx/Rx FIFO, rich GPIO and interruption sources, Duty Cycle Operation Mode, Carrier Sensing, high accuracy RSSI, Low Battery Detection, Power Up Reset, Low Frequency Oscillator Clock Output, Fast Frequency Hopping and Muting Functions, making the application design more flexible, differentiating the end product. The CMT2300A operates from a supply voltage of 1.8 to 3.6 V. It consumes only 6.9 mA current while achieving 120 dBm receiving sensitivity and consumes only 300 nA in sleep state, which makes it an ideal solution for battery powered application. Transmitting at 13 dBm only consumes 27 mA.
