General Description

The TH72032 ASK transmitter IC is designed for applications in the European 868 MHz industrial-scientific-

medical (ISM) band, according to the EN 300 220 telecommunications standard. It can also be used for any

other system with carrier frequencies ranging from 850 MHz to 930 MHz (e.g. for applications in the US 902

to 928 MHz ISM band).

grated PLL synthesizer ensures that each RF value, ranging from 850 MHz to 930 MHz, can be achieved.
