300MHz-to-450MHz Low-Power,
Crystal-Based ASK Transmitter
General Description
The MAX1472 is a crystal-referenced phase-locked
loop (PLL) VHF/UHF transmitter designed to transmit
OOK/ASK data in the 300MHz to 450MHz frequency
range. The MAX1472 supports data rates up to
100kbps, and adjustable output power to more than
+10dBm into a 50 ? load. The crystal-based architec-
ture of the MAX1472 eliminates many of the common
problems with SAW transmitters by providing greater
modulation depth, faster frequency settling, higher
tolerance of the transmit frequency, and reduced
temperature dependence. Combined, these improve-
ments enable better overall receiver performance when
using a superheterodyne receiver such as the MAX1470
or MAX1473.
The MAX1472 is available in a 3mm x 3mm 8-pin
SOT23 package and is specified for the automotive
(-40°C to +125°C) temperature range. An evaluation kit
is available. Contact Maxim Integrated Products for
more information.
