Passband bandwidth
Web3 Feb 2024 · An Nth-order tunable bandpass filter (BPF) structure with extended passband bandwidth has been proposed in this paper based on the novel tunable resonator and coupling structure. The designed tunable resonator is composed of two coupled lines and one varactor diode, while the presented tunable coupling structure is constructed by two … In electronics and signal processing, a filter is usually a two-port circuit or device which removes frequency components of a signal (an alternating voltage or current). A band-pass filter allows through components in a specified band of frequencies, called its passband but blocks components with frequencies above or below this band. This contrasts with a high-pass filter, which allows through components with frequencies above a specific frequency, and a low-pass fi…

Web9 Apr 2024 · This is perhaps best seen in the linear scale plot. In some parts of the transponder bandwidth the noise floor has dropped very little, while close to the right edge it has dropped from 1.75 to 1.5. This is actually a power drop from 0.75 to 0.5, since the receiver thermal noise has a power of 1.
