A Dual-passband Waveguide Filter with a Canonical Structure for Ka-band Satellite Applications

This article presents the implementation techniques for a six-pole, dual-passband waveguide filter with an asymmetric canonical structure for Ka-band satellite applications. An asymmetric canonical structure is chosen, not only to increase the transmis...

For the effective use of the available frequency spectrums, the channels of conventional communications satellite systems are allocated contiguously in frequency. Each channel is filtered by a channel filter with high frequency selectivity, amplified by a high power amplifier and transmitted to the ground through a single beam. Modern...
