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.

Millimeter-Wave Waveguide Diplexer
2020 45th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), 2020This paper presents a rectangular waveguide diplexer based on a T-junction can separate a common input signal into two distanced channels at millimeter-wave (mm-wave) spectrum. This diplexer is capable of separating of two channels operating at the frequencies 116 GHz and 183 GHz providing passbands of 4 GHz and 16 GHz for these two channels ...

Magnetless nonreciprocal filtering diplexing antenna
Microwave and Optical Technology Letters, 2021AbstractThis paper presents a magnetless nonreciprocal diplexing antenna that uses time modulation. The device combines the functions of diplexers, filters, isolators, and antennas in a highly integrated manner. The magnetless nonreciprocity response is achieved by applying time modulation to the resonators of the filtering structures. These resonators

Adjusted multichannel frequency diplexer
International Journal of Infrared and Millimeter Waves, 1996Relatively simple and practical way to construct multichannel diplexer using dielectric resonators placed on substrate with multiple microstrip have been developed. Band-passes less than 160 MGz at level −25 dB have been obtained using multimode structure. Further work must be done to use connected resonators.

In this chapter, the microstrip square open-loop resonator (SOLR) has been utilised in the implementation of the microwave diplexer circuit model established in Chapter 4. The SOLR is very popular and well known resonator type commonly used in the implementation of microwave passive devices including filters and diplexers, due to its compact size.

Diplexer Operation of Stripline Y Circulators: Part 1--Basic Performance of Diplexer Operation
IEEE Transactions on Microwave Theory and Techniques, 1980The diplexer operation as another version of tbe double circulation frequency operation (DCFO) was recently performed with stripline Y-junction loaded with conductor-ferrite (CF) composites. Experimental results demonstrated that the large insertion Iosses appeared in association with higher order circulations. This paper treats circulation adjustments
