Transmitter IC - CMT2119AW


The CMT2119AW is a high performance, extremely flexible and low-cost FSK / OOK RF transmitter chipset designed for various wireless applications from 240-960 MHz. The CMT2119AW is the easiest way to control data transmission.
Transmission is initiated when an effective level change is detected on the DATA-pin, while the transmission action stops after maintaining the level of the DATA-pin for a defined time window.

The CMT2119AW transmitter associated with the CMT2219A receiver enables a robust RF link to be established.
