BSRF FA-1 Filtered Amplifier
The BSRF FA-1 is a filtered amplifier with fail-safe that helps your RF equipment when it faces interference from walkies, DECT, Wi-Fi, GSM/4G, or intercom base stations.
The filter comes before the amplifier to reduce out-of-band interference. Selectable gain steps of +6, +9, and +12 dB make up for loss in coaxial cable, and the BP (bypass) position routes the signal through the filter alone, with no gain. The filter covers your choice of one 50 MHz block: 470-520 MHz, 520-570 MHz, or 570-620 MHz.
Power arrives through DC feed, from an antenna splitter such as the BSRF AS-62 or AS-122, or directly from a rackmount receiver with DC feed. With no power available, the fail-safe puts the FA-1 in bypass mode, where it works like a passive filter. DC also passes through the unit.
