BSRF FA-1

BSRF FA-1

The BSRF FA-1 is a filtered inline amplifier with DC-feed, designed to reduce external interference and compensate for losses in coaxial cables. This device is suitable for both passive and active antennas.

Key Features

• Filtering before amplification to reduce outband interference.
• Four amplification steps.
• Fail-safe functionality: operates as a passive filter without power.
• Can be used to filter the output of an amplifier (up to 1W).
• High linearity amplifier.
• Supports DC through.
• Custom filters available on request.

Specifications

• Frequency bands:
  • Band 1: 470-520 MHz @ -3 dB
  • Band 2: 520-570 MHz @ -3 dB
  • Band 3: 570-620 MHz @ -3 dB
  • Band 4: 620-670 MHz @ -3 dB
• Filter bandwidths: 20/35/60/120 MHz @ -3 dB (customizable).
• Gain: 0 dB to +12 dB with DC feed; -2 dB typical without DC feed (depends on filter width).
• DC feed: 10-18V, up to 200 mA.
• RF input/output: BNC / N (optional), 50 ohms.
• Power supply: 10-18V, 100 mA typical.
• Dimensions: 94 x 20 x 24 mm (including connectors).
• Weight: 100 g.

The FA-1 offers flexibility for use with receivers and IEM systems and can function as a passive filtering solution when not powered.
