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

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.
