==========High-concerned chemical : NoModel Number : Low Pass cleaningOrigin : China

• Combining two core functions: integrating signal filtering and power amplification, achieving clutter suppression and signal enhancement in a single process.
• Multiple filtering types are available: low-pass, high-pass, band-pass, band-stop, and other types are supported, allowing for precise filtering of target signal frequency bands.
• Wide frequency range adaptation: Operating frequency covers 20Hz-1GHz, meeting the needs of multiple scenarios such as audio, RF, industrial control, etc.
• Adjustable high amplification gain: The gain range spans from 10dB to 60dB, allowing for precise adjustment and stable amplification even for weak signals.
• Low-noise operation design: noise figure ≤2.5dB, no additional noise during amplification process, high signal purity.
• Wide voltage power supply compatibility: Supports 12V/24V DC and 110V/220V AC, adapting to different power supply environments.
