Bandpass Filterdesignpractical importanceOptical bandwidth of bandpass filter with metamaterial based defected one-dimensional photonic crystal is analytically computed. Two different metamaterial namely parallel nanorod and nano-fishnet with elliptical void are considered for the design of bandpass filter, and...
In a superheterodyne receiver the channel bandwidth is primarily determined by the IF bandpass filter, whose minimum bandwidth in a double sideband receiver is twice the Nyquist bandwidth. Approaching this lower limit of bandwidth is possible only using high cutoff filters that have a constant delay ...

We have investigated the self-lasing effect of the linear multiwavelength Brillouin-Erbium fiber laser with different tunable bandpass filter's bandwidth. Two 3dB bandwidth of 1 nm and 3 nm filter were used in this study. The experimental results show that the width of the TBF bandwidth plays ...
A tunable bandpass-to-bandstop filter with controllable bandwidth is proposed in this article. The bandpass-to-bandstop transformation can be achieved by adjusting the PIN diode, and bandwidth of the bandpass filter can be controlled by adjusting the voltage of varactors, as the coupling coefficients...

A novel compact dual-band bandpass filter (BPF) based on short stub-loaded stepped impedance resonator (SSL-SIR) and a pair of tri-section stepped impedance resonator (T-SIR) is presented. The dual-band BPF can be divided into two sub filters. The upper sub filter creates the first passba...
Integration of optimized low-pass filters in a bandpass filter for out-of-band improvement 4 shunt-stub filters implemented in classical semilumped low-pass architectures. Then, we investigate alternative integra...
A novel dual-band bandpass filter with large bandwidth ratio is proposed by using two dual-mode square ring resonators. By stretching the length of the loaded open stub of the inner ring, one of its first-order degenerate modes moves down and forms the first passband together with a pair of...
