The DF-A0157 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 RS-485 serial interface to allow remote control over a distance of up to 500m. All switching is solid state for rapid and
unlimited switching cycles.
The DF-A0157 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.
