AC4490 Proprietary 900MHz Radio Module Features:

Lowest cost one-watt module available
"Long range" mode enables 40 miles
High 900MHz data rate: 115.2 kbps
Small form factor: 1.65 x 1.9 inches
Operates in –40°C to +80°C temperatures
Variable output power: 5mW to 1000mW

Compact AC4490 900MHz transceivers can replace miles of cable in harsh industrial environments. Using field-proven FHSS technology that needs no additional site licensing*, AC4490s reject interference, enable co-located system operation, increase output power and maintain data integrity.
AC4490s feature drop-in installation and a number of on-the-fly control commands, providing OEMs with a versatile interface for any application. They can be used as direct wire replacements, requiring no special host software for communication. All frequency hopping, synchronization and RF system data transmission/reception is performed by the transceiver.
AC4490 modules are socket-compatible with AeroComm's 2.4GHz AC4424 transceivers, enabling OEMs to design once and subsequently interchange radios to accommodate new markets, regulations and environments.
