Abstract-An improved E -plane power divider for compact waveguide triplexers with large separation between channels is presented. The configuration of the divider aims to exploit the different behavior of the device for frequency bands with large separation, leading to a very asymmetric E -plane junction. H -plane filters with inductive windows are used for each channel, in order to obtain reduced insertion losses and lower sensitivity than in metal-insert E -plane filters. The resultant triplexer configuration is very compact, and its design is analyzed and optimized by Mode-Matching. The experimental results of a full Ku-band prototype for communications satellite systems show a very good agreement with the expected simulated response.

Abstract-A triplexer for ultra-wideband radio implemented entirely with distributed microstrips is presented. The triplexer is composed of a triplex junction network and three bandpass filters. The circuit is integrated in a flex-rigid printed circuit board. Three flat 1 GHz sub-bands in the frequency band 6-9 GHz have been achieved. The group delay variation within each 1 GHz sub-band was measured to be less than 0.4 ns. A good agreement between simulation and measurement was obtained, e.g., less than 0.3 dB difference in the forward transmission in the majority of the frequency band.

“…Several passive circuits are devised for the realization of MUX, such as circulator coupled MUX, manifold coupled MUX, directional coupled MUX and hybrid coupled MUX [1][2][3][4]. The main required characteristics of MUXs are low volume, capability of integration, desired in-band and out-ofband frequency response and in some cases ultra wideband performance.…”

In this work, a novel circuit topology is introduced for the implementation of multiplexers and demultiplexers, called ''active distributed (de)multiplexers.'' The desired characteristics of active distributed (de)multiplexers as being wideband, planar and active are realized by the proposed microwave circuit. A numerical methodology is presented for its design. An active distributed detriplexer is designed, simulated, fabricated, and measured by the proposed numerical procedure. Computer simulation and measurement results show the effectiveness and suitability of the proposed topology as a detriplexer.
