A new miniature all-inclusive 900MHz FHSS transceiver breaks new ground in the short-range wireless market. The one-inch-square module becomes the key component for creating local RF networks where tight space, low power and limited resources are the OEM's biggest concerns. AeroComm reckons the AC4490-1x1 is so comprehensive that engineers of varying RF experience can design-in full wireless capability with minimal effort.
All components, including firmware, are integrated into its sleek multichip-module design.
Development is straightforward: modules and antennas are simply mounted into place (via hand-solder or surface-mounted with automatic pick-and-place equipment), then powered on.
No special host software is required; 1x1s directly appear to the system as cables.
The modules contain AeroComm's RF232 embedded protocol, which allows for plug-and-play installation.
RF232 guarantees successful communication while making the process invisible to the OEM.
Over-the-air issues are managed in the firmware to synchronise, hop, gain acknowledgements, send retries, detect errors, address messages, secure transmissions and other features unique to RF that newcomers may overlook.
The 1x1's standard TTL serial interface provides bidirectional communication in point-to-point, point-to-multipoint, or multi-to-multi networks.
A number of on-the-fly control commands accommodate varying wireless applications.
Using field-proven proprietary FHSS technology, 1x1s provide interference rejection, enable colocated system operation, increase output power, and maintain data integrity.
Despite their small size, 1x1 transceivers are packed with versatility: up to 115.2Kbit/s serial interface datarate; 1 to 10mW variable output power; two digital input lines; two digital output lines; one A/D input line; one D/A output line; -40 to +80C industrial temperature durability; and priced lower than any other inclusive 900MHz module - less than $20 each in volume.
"The 1x1 is our response to market demand for more powerful features in ever-smaller, less expensive transceivers", said AeroComm CEO Michael Varady.
"By providing a robust product at a fraction of the size and price of comparable modules, we aim to make RF practical for any application.
Our distinct combination of higher integration and higher intelligence promises current and future wireless success to OEMs of all backgrounds".
As the industry's smallest, most complete product, AC4490-1x1 is targeted primarily at industrial and commercial battery-powered applications such as meter reading, building controls, point of sale and home automation.
The 1x1 can be used in portable, mobile and fixed applications in the USA, Canada, Australia and South America.
The modules will be available from AeroComm, Avnet and premier distributors worldwide.
