Compact Microstrip Narrow Bandpass Filter with Good Selectivity and Wide Stopband Rejection for Ku-Band Applications
A new microstrip narrow bandpass filter with good selectivity and wide stopband rejection for Ku-band application is proposed in this letter. The characteristic of the triple-mode stub-loaded resonator has been investigated. The resonance frequencies of the degenerate modes can be adjusted easily to satisfy the bandwidth of the narrow bandpass filter. Two parallel-coupling feed structures with ...
متن کاملWide Tuning Range Active RF Bandpass Filter with MOS Varactors
The paper presents an improved tuning method implemented for a differential active inductor based RF bandpass filter. Derived from a previous designed transistor-only second order filter topology, independent frequency and quality factor tuning are demonstrated in 0.18 μm CMOS technology. The circuit has been basically designed for a maximum frequency of 2.4 GHz, high enough to cover the main w...
متن کاملCompact Bandpass Filter with Wide Upper- Stopband Based on Spiral-shaped Resonators and Spur-lines
A novel compact bandpass filter (BPF) with wide upperstopband has been proposed in this paper. The structure is based on spiral-shaped resonators. Cross coupling is used to generate two transmission zeros at the lower and upper stopbands. Therefore, the out-of-band performance is improved. In addition, two spur-lines are adopted in the feed lines to reject the spurious response. The central fre...
متن کاملCompact Hairpin Bandpass Filter with Wide Stopband and High Attenuation Using Multilayer Broadside-coupled Stripline
This paper presents a compact bandpass filter with stopband and high attenuation by using multilayer folded broadside-coupled quarter-wavelength stripline resonators in a low-temperature co-fired ceramic (LTCC) substrate. The proposed bandpass filter centered at 1.1 GHz with a fractional bandwith of 4.5 % shows the first spurious frequency at 3.8 times the center frequency. In comparison to the...
متن کاملA Novel Compact Suspended Double Side Cmrc Millimeter Bandpass Filter with Wide Stopband
This paper presents a novel compact suspended double side millimeter bandpass filter (BPF) with wide stopband using Suspended Compact Microstrip Resonant Cell (SCMRC). For SCMRC exhibits slow-wave band-stop characteristics, two distributed SCMRC structures are designed to achieve wide stopband characteristic. By applying SCMRC structure and double side design, this novel BPF is size reduced. Ba...
