MAX7044 300MHz to 450MHz ASK Transmitter Datasheet
The MAX7044 is a highly integrated ASK transmitter designed for the 300MHz to 450MHz frequency range. It utilizes a crystal-based architecture to provide greater modulation depth, faster frequency settling, and reduced temperature dependence compared to SAW-based transmitters.
The device features a low supply voltage operation from +2.1V to +3.6V and draws only 7.7mA typical operating current at 2.7V. It includes an automatic shutdown mode that places the device in low-power mode if the data input has not toggled for a specific wait time.
