Fast Tuned Notch Filters

Teledyne Microwave UK’s range of Fast Tuned Notch Filters (FTNF) has been designed to protect Electronic Support Measures (ESM) receivers from high-duty cycle, frequency agile interference produced by onboard (or cohort) combat radar systems. ESM sensors often need protection from high-power nearby radars, and such signals can reduce receiver dynamic range.
