Tunable Active Dual-Band Bandpass Filter Design Using MMIC Technology
Abstract— The inductor-less designing of monolithic tunable active dual-band bandpass filter is presented in this study. Biasing voltages signify main role. They can control the center frequency and quality factor. Using four biasing voltages and cascading two similar filters leads to dual-band bandpass filter. By keeping the gain constant, the center frequency shift is 200 MHz. Regardless cons...
متن کاملA Dual-band Bandpass Filter with a Tunable Passband
Abstract—In this paper, a novel dual-band bandpass filter with a tunable passband is proposed. Based on two quarter-wavelength resonators and one half-wavelength resonator, dual-band character is designed by introducing two independent coupling paths. The filter structure is designed and can be divided into two parts. The Transmission Zeros (TZs) are derived through simulation. By varying the r...
متن کاملDual-Band Band-Pass Filter with Fixed Low Band and Fluidically-Tunable High Band
In this work, we present a dual-band band-pass filter with fixed low-band resonant frequency and tunable high-band resonant frequency. The proposed filter consists of two split-ring resonators (SRRs) with a stub and microfluidic channels. The lower resonant frequency is determined by the length of the SRR alone, whereas the higher resonant frequency is determined by the lengths of the SRR and t...
متن کاملDual-Band Evanescent-Mode Substrate Integrated Waveguide Band-pass Filter for WLAN Applications
A new multi-layer substrate integrated waveguide (SIW) structure is developed to design dual-band evanescent-mode band-pass filters (BPFs). Two independent series LC circuits are implemented by incorporating metallic irises in the different layers of the structure. The combination of the metallic irises with capacitive-plates is embedded inside the SIW to independently excite two evane...
متن کاملAn externally tunable bacterial band-pass filter.
The current paradigm for tuning synthetic biological systems is through re-engineering system components. Biological systems designed with the inherent ability to be tuned by external stimuli will be more versatile. We engineered Escherichia coli cells to behave as an externally tunable band-pass filter for enzyme activity and small molecules. The band's location can be positioned within a rang...
