20GHz-67GHz Millimetre Wave Filters - High Quality, Fully Specified Filters
Characteristics and Application
Millimetre wave filters are used to process signals in the millimetre band and have a high operating frequency as well as frequency selectivity. Millimetre-wave filters require high-precision machining techniques in their manufacture to ensure the performance and reliability of the filters. The short millimetre wavelength makes millimetre wave filters relatively small in physical size, portable and easy to install, and easy to integrate with other microwave devices.
