Tunable Notch Filters
The Netcom tunable Notch filters are designed with multiple independent lumped element notch filters in series. The design topology for this line was selected to achieve constant absolute bandwidth over the corresponding frequency range. Each element can be programmed to turn on or off independently. The major advantage of these product is that using temperature compensation intelligence, the filter internally regulates any frequency drift caused by temperature change and adjusts the notch center automatically to meet rejection requirements.
