New concepts in microwave filters, phasers and multifunctional passive circuits for future RF systems
The focus of the research project are a new concepts of microwave filters, phasers and multifunctional and reconfigurable passive components for use in future RF wireless communication
systems.
The high frequency passive components are of interest in emerging RF chains to be used in
novel communications and radar systems, and Internet of Thing (IoT) sensors for humancentered wireless scenarios. Those components play a key role to enable high efficiency of the
system, for example to maximize the data rate available in communication channel. Microwave
filters allow one to separate the systems that operate on neighboring frequency bands and limit
the interference between those systems. Phasers are the elements of real-time analog signal
processing (ASP), that is an alternative to digital signal processing (DSP) techniques and allows
for manipulating the signal directly in time domain with low cost and low energy. Phasors can
operate in broad frequency range and have potential application in future high frequency
electronic systems, but to process the signal a techniques to realize the arbitrary, user defined
group delay characteristics are needed. Finally, multi-functional and reconfigurable, tunable
components have been developed for performing more-efficient RF-analog-processing multiactions with spectral agility towards their use in highly-versatile RF front ends. Whereas
frequency reconfiguration will be essential in future RF systems, benefits of the multi-functional
philosophy are also manifold as follows: (i) higher physical compactness, (ii) power-insertionloss reduction due to the avoidance of inter-connecting RF interfaces between the monofunctional blocks, and (iii) enhanced electrical performance.
The aim of this work is to develop a new theory of operation and effective design algorithms for
new classes of aforementioned passive components and finally use them to design, realize and
measure microwave passive components with improved electrical performance.
A key idea that enables us to develop a new classes of passive components is to realize them
as coupled-resonator networks that exploit new coupling schemes and frequency dependent
couplings. In this project we aim to use frequency dependent of higher orders - quadratic or even
nonlinear function of frequency. Finding suitable solutions within this project will enable us to go
beyond the state-of-the art of microwave coupled-cavity filter and phaser design.
