​CMT2156AW

OOK Transmitter Targeting for Micro-energy-harvesting

Description

Built in a high-performance OOK RF transmitter, the CMT2156A is a transmitter chip targeting for micro-energy-harvesting applications in 240 - 480 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 CMT2156A co-working with CMT221x series receiving-only receiver can achieve low-cost and environment-friendly battery-free solutions for remote control applications.
