DF-A0054 is a high-speed solid-state four-band, five-channel DF band switch with amplification and ESD protection, controlled by RS-485 commands.
The switch accepts four frequency bands, each with 5 antenna elements. Full frequency range is 1-6000 MHz. Switches route any element of a selected band of five elements (each equipped with input power limiters, ESD protection and low noise amplifier) to that band’s output.
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 many Alaris direction finding antennas, particularly the DF-A0095.
