The RFI UHF Preselector Bandpass Filter is a high-performance RF filter designed for UHF applications within the 400-420 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 400-420 MHz UHF band, providing high-quality signal filtering with a 1 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.
