The RFI UHF Preselector Bandpass Filter is a high-performance RF filter designed for UHF applications within the 450-470 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 450-470 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.
