16GHz-38GHz Spot Frequency Filters - Fast Switching Of Operating Frequency And Suppression Of Interfering Signals
Characteristics and Application
Point frequency filters are designed for one or several specific frequency signals, and can significantly enhance the signals in that frequency band while suppressing the signals at other frequencies.
XST's point-frequency filters play an important role in the field of signal processing due to their high accuracy, high signal-to-noise ratio, flexibility, and wide range of applications.
