AWPF-1 SERIES - PASSIVE NARROW BAND-PASS FILTERS:

Passive Narrow Band-Pass Filter design for "Ultra RF Protection" applications, providing protection to receiving systems in RF hostile spectrum.

Utmost rejection of unwanted signals, protecting your receiving systems against nearby IEM transmitters, mixer to camera transmitters or from any other unwanted transmitters, the AWPF-1 series passive filters is going to be the most useful RF modules in your sound bag, sound cart or Sound trolley.

The AWPF-1 Series BPF designed to have maximum skirt selectivity(utmost unwanted RF rejection, hence protection of your receiving system) and minimum in-band filter loss. The improvement gained in the receiving system performance compared to "Passive Filter" BPF loss is negligible thanks to unique design techniques used.

The AWPF-1 Series are custom tuned to a number of popular frequency bands for our industry in the frequency range 470-1260MHz in fixed bands. Other frequency ranges and Bandwidths to customer specification is welcomed, BPF filters are custom tuned by hand to a very high accuracy.

The in-line passive BPF is a passive device and requires NO DC power to work, it is easy to set up, the design includes DC pass circuity to power "Active Antennas", a LED indicator is located on the "Antenna IN" panel indicating dc power status.

The AWPF-1 Series is a custom design, CNC machined aluminum box to withstand daily location work, finished in black anodizing with clear laser marked legends for long-term readability.
