Description

The DF-A0135 is a high-speed, 4-band, 5 to 2 antenna commutating switch intended for direction finding applications. It accepts four frequency bands, each with 5 antenna elements, and routes any two elements of a selected band to either of the two outputs. The switch is controlled via hardwired logic lines or 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 commutation and unlimited switching cycles.

The DF-A0135 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 systems RF path.

All inputs of the DF-A0135 are equipped with limiters to allow it to operate in harsh EMC environments.
