5722 Notch Filter
The UHF Tunable Notch filter is designed with lumped elements. The design topology for the filter was selected to achieve constant absolute bandwidth over the 225-512MHz frequency range with minimum insertion loss at the passband and peak notch rejection better than 20dB. It can be programmed to turn on (active mode) or off (bypass mode). The tuning frequency step for each notch is 200 kHz (tuning resolution). The filter is equipped with internal temperature compensation that regulates the Temperature Drift of the Notch Frequency keeping it in spec at all temperature conditions.
