A diplexer for UMTS applications
2009 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC), 2009In this article a microstrip diplexer is proposed which has good performance on the UMTS upload and download bands, as shown by simulation results and actual measurements. The diplexer is based on a two-pole resonator named H-type resonator, and makes strong use of cross-coupling to pass energy between ports.

Planar microstrip diplexer for multifunctional antenna
33rd European Microwave Conference Proceedings (IEEE Cat. No.03EX723C), 2003A compact wide-band microstrip diplexer working in the 0.9/spl divide/2.5 GHz frequency range is presented. This component is a key part of the feeding network of a multifunctional antenna, working at five frequency bands associated to terrestrial and satellite radio services.

Quasi-optical diplexer for millimeter wavelengths
Review of Scientific Instruments, 1978A quasi-optical diplexer for injection of signal and local oscillator frequencies into a mixer at millimeter wave-lengths is described. The diplexer accepts both image and signal bands, presents low loss at both the signal and local oscillator frequencies and rejects local oscillator noise at the signal frequency.

High efficiency optical diplexers
Applied Optics, 1982This paper describes various interferometric optical circuits that could provide highly efficient combining of local oscillator and signal beams in heterodyne mixers. Already in use at millimeter wavelengths, they will be of particular importance in optical systems where the available local oscillator power is low.

First-Order Sensitivity of Complementary Diplexers
IEEE Transactions on Circuits and Systems II: Express Briefs, 2004This paper provides sensitivity analysis of complementary diplexers which are used for dividing the frequency spectrum into two adjacent frequency bands. Analytical expressions of the semirelative first-order sensitivity of the transducer losses are derived.

Resonant-Grid Quasi-Optical Diplexers
Bell System Technical Journal, 1975Experimental results are reported concerning the transmission, reflection, and depolarization of metal grids that reflect an upper band, centered at 30 GHz, and transmit a lower band, centered at 20 GHz. With a single grid, the transmission loss is less than 0.1 dB, and the rejection exceeds 44 dB.

Quasi-Optical Polarization Diplexing of Microwaves
Bell System Technical Journal, 1975The feasibility of a microwave quasi-optical polarization diplexer has been demonstrated using photo-etched copper strips with thin mylar backing as a practical example. The insertion losses of the principal polarization and the cross polarization have been calculated and measured. The conducting strips must be aligned in a preferred direction, namely,

Design and Analysis of EMIT Filter and Diplexer
IEEE Transactions on Industrial Electronics, 2017In this paper, a novel design of an E-plane waveguide filter, called electromagnetically induced transparency (EMIT) filter, is proposed. This EMIT filter is implemented by a rectangular ring (RR) on one side of the substrate and two strip lines resonators (SLRs) on the opposite side, which brings in electrically induced transparency and magnetically ...
