TH2A: Innovative planar filters and multiplexers

This session includes five papers, each providing an innovative filter design, using a wide range of planar technologies. These include a technique for providing multi-port power division with a multi-band response, a high-temperature superconducting filter covering two closely spaced bands, a substrate integrated waveguide-based filter, a miniature microstrip filter realized on a very high dielectric constant substrate, and a new type of planar duplexer giving very good transmit-receive isolation.
