“…Diskretinio valdymo įtaisuose paprastai naudojami PIN diodai arba MEMS (angl. microelectromechanical system -MEMS) jungikliai (Llamas-Garro & Brito-Brito, 2010). Papildomų perjungimo elementų naudojimas padidina mikrobangų įtaisų matmenis, struktūra tampa sudėtingesnė.…”

Many microstrip filter configurations exist that exhibit advanced filtering characteristics, rely on new design techniques, or use original methods for filter miniaturization. For each filter type (lowpass, highpass, bandpass, and bandstop), we start with an overview of conventional planar filters, which are often used as a basis for the development of novel configurations, and then proceed to more advanced solutions. We classify the various advanced solutions found in the literature according to the underlying principle of design/operation: i) conventional filters using advanced geometries; ii) filters based on advanced theoretical concepts, such as the slow‐wave effect, defected ground structures (DGSs), electromagnetic‐bandgap (EBG) structures, or metamaterials (MTMs); and iii) filters based on advanced materials and technologies, such as superconducting, ferroelectric materials, and ferromagnetic materials. Finally, we present some of the advanced solutions not covered by the classification given above. We provide an overview of surface‐integrated waveguide (SIW) filters, followed by the discussion of various tunable and reconfigurable filter topologies. In the end, we present state‐of‐the art multiband filters.

In this work, microwave frequency measurement (MFM) is reviewed since the early stages using fully analog implementations, including its evolution to analog/digital implementations with high resolutions up to 1 MHz. The review includes fully digital implementations and microwave photonics techniques, with a discussion on achieved devices and the overall field of measuring and identifying unknown signals. MFM plays a crucial role in electronic warfare, communications, and electronic intelligence systems by identifying the frequency of unknown signals. Several microwave planar devices such as interferometers, filters, and frequency selective surfaces have been proposed to design low-cost and low-power digital MFM systems. The planar devices presented here show resolutions from 1 MHz to 940 MHz and operate in the frequency range from 0.15 GHz to 11.5 GHz, having typical bandwidths from 1 GHz to 2 GHz. MFM using microwave photonics techniques involve mapping the microwave signal into the optical spectrum to create a frequency-power function, that uniquely identifies the frequency of the unknown signal, with large bandwidths and immunity to electromagnetic interference.
