General Description

The TH72002 ASK transmitter IC is designed for applications in the 315 MHz industrial-scientific-medical (ISM) band. It can also be

used for any other system with carrier frequencies ranging from 290 MHz to 350 MHz.

ensures that each RF value, ranging from 290 MHz to 350 MHz, can be achieved by using a crystal with a reference frequency
