“…With the increase in frequency and the application of ultra-wideband circuits, various new integrated transmission line equalizer structures have emerged. In [11], a microstrip equalizer is designed by λ/4 length shunt short-circuit stubs around an R-C parallel resonating circuit. In [12], by employing open SIRs to adjust the equalization slope parameters, a microstrip equalizer is achieved.…”

This paper proposes the design of a microwave equalizer based on stepped impedance resonator (SIR) loading with an internal coupled-line. By loading a ring-type stepped impedance resonator (SIR) with internal coupled-lines, a microwave equalizer with positive slope transmission characteristics is presented. The frequency response is synthesized using a second-order SIR, and a detailed theoretical derivation of the equalizer is presented. A prototype of the equalizer is fabricated and measured to validate its expected performance, with the measurements showing good agreement with the predictions. The microwave amplitude equalizer demonstrates the necessary gain slope across its entire operational frequency range. Finally, a potential design scheme for a microwave amplitude equalizer is proposed.

“…Various types of broadband CPW-to-RWG transitions have been proposed in the literature [1][2][3][4][5][6][7][8][9][10][11][12][13]. Since 1990, ridge waveguide has been used to accomplish broadband CPW-to-RWG transitions [1][2][3][4][5].…”

“…However, the size of the ride waveguide is large, and the mechanical process used to fabricate the ridge waveguide is complicated, increasing the transition cost. To tackle the complex fabrication process of the ridge waveguide, CPW-to-RWG transitions using the planar type transitions are proposed [6][7][8][9][10][11][12][13]. First, a broadband CPW-to-RWG transition using the fin-line taper is presented [6].…”

This paper proposes a compact and broadband coplanar waveguide (CPW)-to-rectangular waveguide (RWG) transition using a resonator with an impedance-matching element. The transition size is as small as 7.66 mm, and the frequency range for which the reflection coefficient is smaller than −15 dB covers from 8.05 GHz to 12.18 GHz (FBW = 40.83%), almost encompassing the full Xband (8.2-12.4 GHz). To reduce the size of the transition, a short-circuited stub phase shifter is used to replace the half-wavelength phase shifter, resulting in a miniaturized CPW-to-RWG transition using the resonator with the impedance-matching element. The transition size is further reduced from 7.7 mm to 5.9 mm. Besides, the frequency range for which the reflection coefficient is smaller than −15 dB covers from 8.05 GHz to 12.38 GHz (FBW = 42.38%), nearly encompassing the full X-band (8.2-12.4 GHz) as usual. To verify the simulation results, both CPW-to-RWG transitions using the resonator with the impedance-matching element are fabricated and measured. The simulation and measurement results are in reasonable agreement.
