As a turn-key RF solutions provider, NuWaves offers RF filter design services specializing in high-performance designs and industry-leading lead times, rivaling the industry’s major filter manufacturers in Cavity, Lumped Element, Stripline, and Microstrip custom filter and multiplexer design capabilities. (OKSI), Torrance, CA. The bandpass employs a digitally tunable capacitor (DTC) and allows for tuning of the centre frequency with a resolution of 5 bit. of Multi-Band RF Band Pass Filter Based on Tunable High-Q. Capacitive band-pass filter. A tunable RF bandpass filter is implemented with capacitive termination, and achieves 18 dB maximum attenuation and 1. The tunable band pass filters and band reject filters, also known as band-stop filters or band-rejection filters, are effective in band selection or frequency discrimination with high attenuation greater than 50 dB possible, allowing. The Extended Range Filter has been designed for integration in radio transceivers where small size and low power consumption are paramount. The tunable bandpass filters are five-section, iris coupled 0. These tunable filters are based on two proprietary technologies that utilize athermal multi etalon cavities or gratings, offering attractive features of covering near all wavelength, very low loss, unparallel low cost, set-and-hold operation, wide tuning range, ultrabroad band (visible to LWIR. The resonators of the top coupled topology. The insertion loss is 0. Five selectable bands. The entire thing is much tinier than it looks. Full Article PDF (376 KB) Abstract: This paper presents a third-order digital tunable bandpass filter based on digitally tunable capacitor loaded microstrip open ring resonator. Copy your list of part numbers from any document and paste them in the text box below. A programmable high frequency (HF) bandpass filter is disclosed. AU - Li, L. “But with coexistence and interference issues on the rise, we can.
