LP Series MLO low-pass filters. Source: AVX. AVX Corporation has released a series of low-profile, low-pass filters with best-in-class performance. Based on AVX’s multi-layer, organic (MLO®), high-density interconnect technology, the LP Series MLO low-pass filters utilize a combination of high dielectric constant and low loss materials to enable the fabrication of multi-layer, stacked passive devices, such as inductors and capacitors, with high volumetric efficiency, high Q and exceptional electrical performance.
Designed to support both a wide frequency range (0.4 GHz–6.5 GHz) and several wireless standards, LP Series low-pass filters feature an ultra-low 0.55 mm height profile, and exhibit excellent isolation, low insertion loss (≤1.3 dB), low parasitics and 50 Ω impedance, making them ideal for use in various wireless applications, including mobile communication devices, global positioning systems, vehicle location systems, wireless LANs, satellite receivers and instrumentation.
The low-pass filters also deliver improved reliability over standard silicon and ceramic devices, including low-temperature, co-fired ceramic (LTCC) devices, which can also be used to realize multi-layer stacked passives.
The filters are currently available in four footprints with varying lengths (6.57 mm, 7.38 mm, 8.67 mm, and 10.19 mm, ±0.10 mm) and fixed widths and heights (3.97 mm and 0.55 mm, ±0.10 mm, respectively). They are supplied with gold terminations that are compatible with automatic soldering technologies, including reflow, wave soldering, vapor phase and manual.
The series is rated for operating temperatures spanning –55° C to +85° C, is 100% tested for electrical parameters, and can be shipped in waffle or bulk packaging. Lead time for the series is 12 weeks.
