Abstract
A Chebyshev time-delay three-pole bandpass filter has been developed in the 900-MHz band by using the Q control method of normal modes. The group delay ripple of the filter is 50 ns within the 300-kHz bandwidth. The size of the equipment is 482.0-mm wide*300.0-mm deep*132.6-mm high, and it can be put into a 19-in standard rack. This filter is expected to be applicable for channel filters used in digital cellular base stations.<>Keywords
