TL;DR: In this article, a new class of broadband and fully 3D printed $E$ -plane coax-to-waveguide transition and a monolithically 3-D printed waveguide magic-T based on the transition are presented.

TL;DR: A waveguide step-twist integrated with a bandpass filter is presented in this article, where the twist is composed of four equally rotated cavities to achieve polarisation rotation and filtering functionalities simultaneously.

TL;DR: In this article, the authors extend the conventional coupling matrix theory for passive filters to the design of "filter-amplifiers", which have both filtering and amplification functionality, based on the specification of the filter and small-signal parameters of the transistor.

TL;DR: This article presents a fourth-order slotted spherical resonator waveguide bandpass filter (BPF) with a wide spurious suppression stopband that uses the first higher-order TM< sub>211 mode rather than the fundamental TM₁₀₁, to obtain a higher unload quality factor and better tolerance to fabrication errors in high frequency applications.

TL;DR: In this paper, an integrated waveguide filter amplifier using all resonator-based filtering and matching structure is presented, and an active coupling matrix is proposed for the first time to describe the coupling topology.
