International Journal of Infrared and Millimeter Waves, 1998
The paper describes a band-splitting filter or diplexer, which splits the incoming spectrum into the sub-bands 120-139 GHz and 141-158 GHz. This diplexer is intended to separate the electron cyclotron emission of a magnetically confined plasma into two subbands and to feed two independent heterodyne radiometers.

2014 IEEE MTT-S International Microwave Symposium (IMS2014), 2014
A compact diplexer fabricated on substrate-integrated waveguide (SIW) technology is presented. The diplexer is a coupled-resonator network with no additional elements such as power dividers, composed exclusively of six SIW resonators coupled through inductive irises, with one transmission zero at each channel that improves the selectivity.

Synthesis of wideband waveguide diplexers
2009 International Conference on Electromagnetics in Advanced Applications, 2009A design strategy for high-performance waveguide diplexers is presented in this paper. This technique directly provides the geometry of the two filters starting from the desired frequency response expressed in polynomial form. The dispersive mutual loading effect of the two filters and the various junctions as well as the losses and the multimodal ...

Broadband Diplexed Power Amplifier
IEEE Microwave and Wireless Components Letters, 2020We present a diplexed power amplifier (PA) architecture for achieving more than octave bandwidth with high efficiency. Two relatively narrowband single-stage PAs are connected with a contiguous diplexer-combiner network. The average efficiency across the larger than octave band is maintained with a flat gain response from 1.8 to 4 GHz.

QUASIOPTICAL POLARIZATION MULTIPATH DIPLEXER
International Journal of Infrared and Millimeter Waves, 2006Development of quasioptical polarizational multipath diplexer has been presented. Calculation and measurement of transmission characteristics of diplexer for various angles of mutual rotation of polarizing elements have been demonstrated. The possibility of considerable improvement of diplexer characteristics by means of correction of phase front with ...

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.

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 ...
