DC-40GHz Low Pass Filters - RF & Microwave Industry Experts
Characteristics and Application
XST's low-pass filters allow signals below the cut-off frequency to pass through smoothly and suppress signals above the cut-off frequency, thus effectively filtering out high-frequency noise and improving signal quality.XST offers low-pass filters in the frequency range of DC-40GHz to meet the needs of different application scenarios.
