Ultra-low Power Sub-1GHz RF Transceiver
1. Descriptions of RF Transceiver IC CMT2300AW:
CMT2300A is an ultra-low power, high performance, OOK (G) FSK RF transceiver suitable for a variety of 140 to 1020 MHz wireless applications. It is part of the CMOSTEK NextGenRFTM RF product line. The product line contains the complete transmitters, receivers and transceivers. The high integration of CMT2300A simplifies the peripheral materials required in the system design. Up to +20 dBmTx Power and -121 dBm sensitivity optimize the performance of the application. It supports a variety of packet formats and codec methods to meet the needs of various different applications. In addition, CMT2300A also supports 64-byte Tx/Rx FIFO, GPIO and interrupt configuration, Duty-Cycle operation mode, channel sensing, high-precision RSSI, low-voltage detection, power-on reset, low frequency clock output, manual fast frequency hopping, squelch and etc. The features make the application design more flexible and differentiated. CMT2300A operates from 1.8 V to 3.6 V. Only 8.5 mA current is consumed when the sensitivity is -121 dBm, SuperLow Power mode can further reduce the chip power consumption. Only 23mA Tx current is consumed when the output power is 13 dBm.
