The Overview
Kyocera AVX's HP Series of high-pass, thin-film filters offer reliable and repeatable performance as well as low insertion losses, very sharp roll-off values, and steep attenuation. Five part numbers are available in 0805-size packages.
Who Needs It & Why?
These thin-film filters are optimized for use on the small, densely populated PCBs typically designed for next-generation wireless applications. Because they're based on multilayer thin-film technology, the filters can be quickly adjusted by Kyocera AVX in terms of RF parameters, yielding custom filters with a short lead time.
Under the Hood
HP Series filters are offered in models optimized for 2.70, 2.80, 2.90, 3.00, and 5.15 GHz, enabling broad compatibility with high-frequency wireless systems, including 5G and UWB applications. Because the parts are rated at 15 W, they can also be deployed in high-power remote radio units in base stations as well as in defense applications.
Their overall operating frequency range is 1 to 5.15 GHz and they tolerate a broad temperature range of –40 to +85°C. Characteristic impedance is 50 Ω. The filters exhibit high temperature stability and lot-to-lot as well as part-to-part consistency. They also offer rugged, miniature, and low-profile construction that's suitable for automated assembly. Packages measure 2.03 mm long × 1.55 mm wide × 0.8 mm tall (±0.1 mm) and the parts offer a continuous power rating of 3 W.
