RF High Pass Filters-Size, Connector Type, Material, Frequency Range Can Be Customised
Characteristics and Application
Our high pass filters cover a wide frequency range and are able to clearly differentiate between low and high frequencies in a signal. The passband flat stopband efficiently blocks unwanted low frequency signals to improve signal purity and signal-to-noise ratio. Small in size, light in weight and easy to install, XST offers flexible high pass filter customisation options in the 100MHz-40GHz frequency range to meet individual customer requirements.
