AeroComm AC4490-1x1 900MHz RF TransceiverAeroComm AC4490-1x1 900MHz RF Transceiver

  • Smallest complete transceiver on the market.
  • High data rate: Up to 115.2 Kbps.
  • Easiest installation: protocol included.
  • Durable in -40°C to +80°C industrial temps.
  • Low power for battery-operated products.
  • Less than $20 in volume.

Tiny 1x1-inch 900MHz modules will put the power of wireless into the smallest, most cost-sensitive applications. Despite their amazing size, 1x1s can replace a mile of cable even in harsh industrial conditions.

Thanks to its RF232 embedded protocol, 1x1 integration is painless. OEMs simply solder the transceivers and antennas into place, then power-on. All frequency hopping, synchronization, and RF system data transmission/reception is performed in the firmware.

1x1's standard TTL serial interface provides bi-directional communication in point-to-point, point-to-multipoint and multipoint-to-multipoint networks. A number of on-the-fly control commands accommodate varying wireless applications.

1x1 is the solution for OEMs working with tight space and limited resources. Popular concerns such as size, speed, range, power, reliability and cost are all covered here — making wireless practical for almost any high-volume application.
