DF-A0226
High-Speed DF Antenna Band Switch
The DF-A0226 is a high-speed, 4-band switch intended for direction finding applications. It accepts four frequency bands, each with five antenna elements, and outputs the elements of any one band to the corresponding five RF outputs. The switch is controlled via ethernet or an RS-485 serial interface to allow remote control over a distance up to 500m. Band switching can also be accomplished via direct differential pair switching for higher speed if needed All switching is solid state for rapid and unlimited switching cycles. The DF-A0226 includes an internal noise source as well as an external input for chain calibration purposes. Either the internal noise source or the external calibration input may be selected to simultaneously inject a balanced signal in place of the antenna inputs and thereby correct errors caused by variations in the system’s RF path.
