Diplexing Millimeter Waves

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.

SIW compact diplexer

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, 2009
A 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, 2020
We 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, 2006
Development 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, 1978
A 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.
