ATW-F500DE2

The ATW‑F500DE2 is a passive band‑pass filter pair designed primarily for use with wireless microphone systems. It is installed in the signal path between an antenna and a wireless receiver, and is intended to block “out‑of‑band” radio‑frequency signals that could otherwise saturate the front end of the wireless receiver, thereby improving dynamic range and reducing interference.

Key Features

• Passive operation: no power supply or tuning is required.

• Standard BNC‑type connectors for easy integration with antenna/distribution systems.

• Designed as a pair (two filters) for dual antenna or diversity setups.

• Covers a specified frequency band (470–530 MHz) in this model.

• Impedance of 50 Ω, matching common RF equipment.

• Typical insertion (transmission) loss around 4 dB.

• Max current pass‑through: up to 420 mA.
