Integrated circuit wireless RF Transmitter microcontroller IC CMT2159AW6 Integrated circuit wireless RF Transmitter microcontroller IC CMT2159AW


FSK/OOK Transmitter Targeting for Micro-energy-harvesting


Built in a high-performance FSK/OOK RF transmitter, the CMT2159A is a transmitter chip targeting for micro-energy-harvesting applications in 240 - 960 MHz frequency range. The encoder integrated in the chip can adapt to the 1527 and 2262 encoding formats that are commonly used in market as well as the 1920 encoding format defined by CMOSTEKTM . All encoding formats supported by the chip and the RF related configurations can be programmed to the chip EEPROM by users via CMOSTEKTM USB Writer and RFPDK software. As part of CMOSTEK NextGenRFTM series product, the CMT2159A co-working with CMT221x series receiving-only receiver can achieve low-cost and environment-friendly battery-free solutions for remote control applications.
