TL;DR: In this paper, a class of frequency-reconfigurable input-reflectionless/absorptive RF/microwave filters is presented, which consist of tunable complementary-duplexer architectures that are composed of a main and an auxiliary channel with opposite filtering transfer functions.

TL;DR: By embedding transversal signal-interference filtering sections into the arms of conventional Wilkinson-type power-divider topologies, RF/microwave power-distribution actions with intrinsic mono/multi-band bandpass filtering capabilities can be obtained.

TL;DR: In this paper, the authors proposed a balanced quasi-absorptive single/dual-band bandpass filter (BPF) with symmetrical quasi-reflectionless differential-mode behavior.

TL;DR: The theoretical foundations of the engineered balanced filter approach, along with guidelines to design the differential-mode transfer function and to attain optimum in-band common-mode power-attenuation characteristics, are expounded.

TL;DR: In this paper, a single/multi-band coupled-multi-line filtering section and its application to the design of RF filtering devices are presented. But this one-port filtering cell is made up of ${N+1}$ intercoupled quarter-wavelength transmission-line segments for the generation of a transfer function with a total of N + 1}$ transmission zeros (TZs) distributed at both sides of all its first-order passbands when arranged in the transmission mode.
