ROUTING WITH CLASSICAL CORRUGATED WAVEGUIDE LOW-PASS FILTERS WITH EMBEDDED BENDS

Complex low-pass filters

Zero-if transceivers suffer from the imbalance of the I and Q paths. By using a complex low-pass filter topology instead of a conventional pair of real low-pass filters, this imperfection can be reduced. Both analytical and numerical analysis show that the proposed technique is significantly more robust to circuit imperfections than the traditional architecture.

Drawing Simultaneously Embedded Graphs with Few Bends

Adaptive waveguide bends with homogeneous, nonmagnetic, and isotropic materials.

We propose a method for adaptive waveguide bends using homogeneous, nonmagnetic, and isotropic materials, which simplifies the parameters of the bends to the utmost extent. The proposed bend has an adaptive and compact shape because of all the flat boundaries. The nonmagnetic property is realized by selecting OB'/OC = 0.5. Only two nonmagnetic isotropic dielectrics are needed throughout, and th...

Design of Dual-Mode Substrate Integrated Waveguide Band-Pass Filters

Three dual-mode band-pass filters are presented in the present paper. The first filter is realized by dual-mode substrate integrated waveguide (SIW) cavity; the second is based on the integration of SIW cavity with electromagnetic band gap (EBG); and the third is based on the integration of SIW cavity with complementary split ring resonator (CSRR). The dual-mode SIW cavity is designed to have a...

Impedance-matched low-pass stripline filters

We have constructed several impedance-matched low-pass filters using a stripline geometry with a dissipative dielectric. The filters are compact, simple to construct, and operate in cryogenic environments. The dissipative dielectric consists of magnetically-loaded silicone or epoxy, which is commercially available under the trade name Eccosorb. For a stripline length of 32 mm, the filters have ...
