MAX7044 300MHz To 450MHz High-Efficiency, Crystal-Based +13dBm ASK Transmitter

The MAX7044 crystal-referenced phase-locked-loop (PLL) VHF/UHF transmitter is designed to transmit OOK/ASK data in the 300MHz to 450MHz frequency range. The MAX7044 supports data rates up to 100kbps, and provides output power up to +13dBm into a 50 load while only drawing 7.7mA at 2.7V.
The crystal-based architecture of the MAX7044 eliminates many of the common problems with SAW-based transmitters by providing greater modulation depth, faster frequency settling, higher tolerance of the transmit frequency, and reduced temperature dependence. The MAX7044 also features a low supply voltage of +2.1V to +3.6V. These improvements enable better overall receiver performance when using the MAX7044 together with a superheterodyne receiver such as the MAX1470 or MAX1473.
A simple, single-input data Interface and a buffered clock-out signal at 1/16th the crystal frequency make the MAX7044 compatible with almost any Microcontroller or code-hopping generator.
The MAX7044 is available in an 8-pin SOT23 package and is specified over the -40C to +125C automotive temperature range.
