Customised 300MHz-45.5GHz Waveguide Filters / Waveguide Bandpass Filters
Characteristics and Application
Waveguide filters are characterised by high Q, low insertion loss, wide bandwidth coverage, high power handling capability, high interference immunity, good temperature stability, high customisation capability and size optimisation in terms of performance. The excellent performance of waveguide filters makes waveguide filters play an important role in the field of communication, radar and satellite communication.
