| Summary: | This paper presents the design of frequency selective limiting circuit based on nonlinear matched reflectionmode
bandstop resonator. This type of Frequency Selective
Limiters (FSL) can achieve fast switching, high-level of power limiting, and flexible channel bandwidth as well as has the ability to protect the sensitive circuitry against large interfering signals. A prototype first-degree frequency selective limiting circuit based on bandstop response is proposed and designed. The circuit has
the center frequency of 2.4 GHz and is implemented on an FR4
substrate with a thickness of 1.6 mm and dielectric constant
(εr) of 4.7. Experimental results show excellent agreement with simulated performance. This new class of FSL would be useful in microwave systems such as in wideband electronic warfare receiver as multi-channel band-stop filters. |
