General Description
The TH71101 FSK/FM/ASK single-conversion superheterodyne receiver IC is designed for applications in
the European 433 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
300 MHz to 450 MHz (e.g. for applications to FCC part 15 and ARIB STD-T67).
