General Description

The AS3902 is a single channel low power 433 MHz ASK transmitter.

It uses a fully integrated PLL stabilized RF-oscillator which avoids frequency pulling by approaching the antenna with objects as it occurs at SAW resonator based transmitters.

ASK modulation is performed by switching the transmitter on and off by an applied data stream.

Key Features

  • Supports the European 433 MHz ISM band.
  • No frequency pulling by (antenna) load variation due to PLL synthesizer.
  • Designed to be conform to EN 300 220-1 requirements.
  • ASK data rate range from 0 to 32 kbit/s.
  • Supports clock and reset signals for the external µC. Therefore no separate µC XTAL is required.
  • Supports total shut down mode without any running XTAL oscillator.
  • Typically 2 external resistors and 3 capacitors required.
