A waveguide filter is useful for some frequency range passing (the pass-band filter), or – rejecting (the stop-band filter), or limiting from the cut-off frequency value (high-pass or low-pass filter).
Ku-band high-pass filter
This waveguide high-pass filter is used in Ku band for transmitting all frequencies above a cutoff frequency, substantially attenuating frequencies below
Ku-band low-pass filter
This waveguide low-pass filter is used in Ku band for transmitting all frequencies below a cutoff frequency, substantially attenuating frequencies above
Ku-band bandpass filter
This waveguide bandpass filter is used in Ku band for the out of band signal emissions reducing, the signal bandwidth limitation and the transmitter noise-band reducing
