S-Band Fast Tuned Notch Filter ES005 S-Band Fast Tuned Notch Filter The ES005 fast tuned notch filter (FTNF) has been specifically designed to protect ESM receivers from high duty cycle frequency agile interference from on board or cohort combat radar systems. Each FTNF provides two independently controlled notches to suppress multiple interference sources with the added ability to also combine to a single, greater depth notch. The ES005 incorporates temperature correction and integrated auto-calibration circuits. The temperature correction circuit corrects notch centre frequency drift due to operating temperature variations and maintains the FEATURES • • • • • • • S-Band coverage Ultrafast tuning speed <250nS Digital Tuning Control Can be cascaded Low Loss In All Pass State Dual Independently Controlled Notches Very Small Form Factor notch characteristics within the specified limits across the operating temperature range. The ES005 carries out this function automatically during its normal operation independent of customer intervention. The integrated auto-calibration circuit provides the option to re-calibrate the ES005 for any long-term drift of the notch centre frequency. This self-calibration routine is carried out under external command, a single active low input provided by the operator through the MDM connector.
