Abstract

PURPOSE:To improve the dielectric strength of a frequency-sharing wave-guide-type branching filter by using a waffle-type band stop filter, whera a pi filter is formed on the surface of a coupling hole, to form an equivalent short-circuit surface. CONSTITUTION:Waffle-type band stop filter 12 which forms a pi filter is provided between surface A of coupling hole 8 and waffle-type band stop filter 10 which stops a communication frequency, and an equivalent short-circuit surface is formed on coupling hole surface A. The power-proof efficiency of the branching filter constituted in this manner has an electric field near to zero and does not generate voltage destruction on the coupling hole surface because the coupling hole surface is made of the short-circuit surface. Consequently, the dielectric strength can be improved by forming the equivalent short-circuit surface of transmission waves on the coupling hole surface by waffle type band stop filters.
