Product Description

The RFI UHF Preselector Bandpass Filter is a high-performance RF filter designed for UHF applications within the 380-400 MHz range. Its compact, multi-resonator milled aluminum construction makes it ideal for space-constrained environments or installations requiring a 19” rack mount. With a symmetrically sharp skirt response and low passband insertion loss, this filter is well-suited as a preselector in receiver systems or as a post-filter for cleaning up transmitter carriers or Tx sub-bands (power rating dependent). DC grounding at the input and output ports provides natural voltage surge protection, while temperature-stable resonators ensure consistent performance across a wide operational temperature range, even in extreme conditions.

Product Features:

  • This filter is optimized for the 380-400 MHz UHF band, providing high-quality signal filtering with a 4.5 MHz passband.
  • It features sharp symmetrical skirt selectivity.
  • With low insertion loss and ripple, it maintains signal integrity with minimal degradation.
  • It has a compact milled aluminum construction that ensures long-lasting performance.
  • The 2RU 19” rack-mount front panel is detachable, allowing for easy installation.
  • It operates reliably in a wide temperature range from -30ËšC to +60ËšC (-22ËšF to +140ËšF).

Application Areas:

  • Public safety and emergency communication systems.
  • Two-way radio and UHF repeater networks.
  • Broadcast and telecommunication infrastructure.
  • RF interference reduction in critical communication systems.

In the Box:

  • RFI RX3840-1801-32 UHF Preselector Bandpass Filter, 380-400 MHz, 4.5 MHz BW, N-Female.
