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...

Periodically Loaded SSS Coupled-line Filter for Second Harmonic Suppression

A suspended substrate stripline (SSS) filter using coupled-lines with periodical capacitive loading is proposed to suppress the second harmonics. The required capacitive loading is achieved by using elevated circular posts in the filter cavity. An exam...
Rapidly growing wireless systems call for low loss filters with special requirements such as a suppressed second harmonic and a wide stop band region. Although conventional parallel coupled-line filters have many salient features, 1 their spurious response at 2f o make them unsuitable for modern day wireless systems. This...
