An electronic circuit that functions to block or hold signals with intermediate frequencies (median) and will forward signals between low frequencies and high frequencies is the definition of a Notch Filter. The Band Stop Filter, also often referred to as the Notch Filter, is a combination of a Low Pass Filter and a High Pass Filter connected in parallel. This connection differs from the Band Pass Filter, which connects the Low Pass Filter and High Pass Filter in series. This study aims to discuss the simulation of the Sallen-key notch filter Circuit. The author also conducts real simulations to prove the Circuit by changing or adjusting the value of the components installed in the Circuit so that the frequency response is according to the target. The purpose and role of the Sallen-key notch filter and the working principle of the theory of each filter used. The research method used in the research work is to carry out virtual simulations using virtual simulators and live simulations

“…Its operating principle lies in the fact that, with an appropriate choice of length, the open-ended stub acts as a short at the cut-off frequency [1]. A tunable BSF provides many advantages like tunability, compactness, selectivity, cost-effectiveness, and spectrum management in RF and microwave circuits [2], [3]. Stop-band tunability over small ranges includes varactor [4], substrate integrated waveguide (SIW) resonator coupled microstrip line [5], and half mode SIW for flexibly controlled cut-off [6], [7].…”

This paper develops an easy design analysis for a simple high selective T-shaped band-stop filter (BSF) loaded with a capacitance. It applies the developed design theory to obtain an appropriate capacitance value for tuning the cut-off frequency. This paper clearly explains the design mechanism for such a simple tunable BSF using ABCD matrices. Simulated filters loaded with capacitances (up to 1.1 pF) show a change in rejection frequencies from 2 GHz (un-tuned) down to 1.047 GHz with 50dB rejection and around 36% -3dB fractional bandwidth. It also shows the effect on pass frequencies which change from 1 GHz down to 111 MHz, while the separation between pass and stop frequency remains around 1 GHz. Measurements on fabricated prototypes match the simulation and theory for tunable frequencies closely. It also compares the performance of the filter with previously reported similar structures.

High-performance RF transceiver systems create large demands in multimode wireless communication system applications with high-frequency suppression, increased spectral utilization, and flexibility to control stopband and passband frequency characteristics. This review analyzes microstrip bandstop filters mentioned in from recent research articles focusing on their performance characteristics, design techniques and applications. Filters are categorized into five categories, namely, Single stopband bandstop filter, Dual stopband BSF, Wide stopband BSFs, Low pass with Wide stopband BSFs, and reconfigurable filters, this article deals with a study of these filters. An extensive analysis of the filter design techniques including the type of resonators, coupled line sections, open/short-circuited stubs, DGS/DMS, and flexible switching devices has been made with comparison and exploration of the simulated, measured frequency responses in each category.
