Abstract
A capacitive compensation technique is described for the design of microstrip parallel coupled filters with improved passband symmetry and very low spurious response up to 2.5 times the center frequency. The compensated structure does not require any extra computer-aided design tools and is compatible with monolithic microwave integrated circuit technology. The technique is useful for the design of filters on alumina as well as GaAs substrates. Two design examples are considered.<>
