The MAX1479 crystal-referenced phase-locked-loop
(PLL) VHF/UHF transmitter is designed to transmit ASK,
OOK, and FSK data in the 300MHz to 450MHz frequency
range. The MAX1479 supports data rates up to 100kbps
in ASK mode and 20kbps in FSK mode (both
Manchester coded). The device provides an adjustable
output power of more than +10dBm into a 50Ω load. The
crystal-based architecture of the MAX1479 eliminates
many of the common problems of SAW-based transmitters
by providing greater modulation depth, faster frequency
settling, higher tolerance of the transmit
frequency, and reduced temperature dependence.
These improvements enable better overall receiver performance
when using the MAX1479 together with a
superheterodyne receiver such as the MAX1470,
MAX1471, MAX1473, or MAX7033.
The MAX1479 is available in a 16-pin thin QFN package
(3mm x 3mm) and is specified for the automotive
temperature range from -40°C to +125°C.
Applications
Remote Keyless Entry
Tire Pressure Monitoring
Security Systems
Radio-Controlled Toys
Wireless Game Consoles
Wireless Computer Peripherals
Wireless Sensors
RF Remote Controls
Garage Door Openers
