High-Speed DF Antenna Band Switch
DF-A0137
Active
The DF-A0137 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 an EIA-485 (RS-485) serial interface to allow remote control over a distance of up to 500 m. All switching is solid state for rapid and unlimited switching cycles.
