DF-A0052 — Three-band, 5 to 3 Channel DF Switch 1-3600 MHz

Interested in learning more about this product?

DF-A0052 is a solid-state three-band, five to three-channel commutating DF switch with amplification and ESD protection, controlled by RS-485 commands.

The switch accepts three frequency bands, each with 5 antenna elements. Full frequency range is 1-3600 MHz. Switches route any three elements of a selected band of five elements (each equipped with input power limiters, ESD protection and low noise amplifier) to any of the three outputs.

A “calibration band” can also be selected, providing a balanced 5-way split of an internally generated or externally supplied signal, for RF chain and receiver calibration. The switch accepts a wide input voltage range and is controlled via hardwired logic lines or an EIA- 485 (RS-485) interface. All switching is solid state for rapid commutation and unlimited switching cycles.

DF-A0052 can be mounted within the weatherproof electronics cavity of the DF-A0029, DF-A0031 and DF-A0037 direction finding antennas.
