Analog Devices MAX7044 Crystal-Referenced VHF/UHF Transmitter is a Phase-Locked-Loop (PLL) device designed to transmit OOK/ASK data in the 300-450MHz frequency range. The MAX7044 can support data rates up to 100kbps. The transmitter provides output power up to +13dBm into a 50Ω 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. The device has a 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 with a superheterodyne receiver such as the MAX1470 or MAX1473.
