Abstract
A microwave separator for separating a microwave signal to those having frequencies included in two frequency bands by means of a first band pass filter intended for the low frequency band and a second filter intended for the high frequency band, characterized in that said first band pass filter is of the comb line type and that said second band pass filter is of the coaxial type in which plural coaxial type resonators are connected one another in series through capacitors. As the result, microwave signals can be reliably separated at two adjacent frequency bands without any signal loss and the return losses of the band pass filters can be improved accordingly.
