A novel millimeter‐wave gain equalizer using E‐plane microstrip‐line probe and waveguide resonator

Abstract

In this paper, a new millimeter-wave gain equalizer based on metallic rectangular waveguide is presented, which is implemented by E-plane microstrip-line probe, metal rectangular waveguide resonator, waveguide coupling groove, and thin-film resistor. The proposed gain equalizer has good tunability, high Q factor, and high power capacity. To demonstrate its performance, a modified gain equalizer, operating 90 to 97 GHz, is designed and fabricated. The final equalizer has achieved better performance and satisfied the need of actual application under a working range from 90 to 97 GHz.

“…Using CMOS technology, Chen et al designed a millimeter‐wave up‐conversion mixer by using a two‐path transconductance stage and Yu et al reported a linear V‐band low‐noise amplifier by employing a Gm‐boosting technique using full‐wave high‐frequency structure simulator. Other technologies like GaAs MMIC, hybrid integrated circuits, and electric vacuum devices are also presented by Li et al, Yang et al, and Wang et al, respectively. In addition to active and passive device and circuit design, devices for emerging applications like THz sensors and THz absorbers are reported by Cheng et al and Aghaee and Orouji .…”
