New Multilayer Organic High Pass Filters for Wireless Applications

AVX Corporation has released a new series of low profile, high pass filters based on their patented and proven multilayer organic (MLO) high density interconnect technology. The new HF Series MLO high pass filters utilize high dielectric constant and low loss materials to help engineers integrate high Q passive printed elements, such as inductors and capacitors, in multilayer stacks with land grid array surface mount packaging that’s expansion-matched to most organic printed circuit board materials, providing improved reliability over standard silicon and ceramic devices.

Exhibiting low insertion loss, excellent rejection of out of band frequencies, low parasitics, favorable heat dissipation characteristics, and 50 ohm impedance, the new HF Series filters feature an ultralow maximum profile height of 0.559 mm, and support both a wide frequency range (0.74 GHz to 2.83 GHz) and several wireless standards, making them ideal for use a variety of wireless applications, including: mobile communication devices, global positioning systems (GPS), vehicle location systems, wireless local area networks (LANs), satellite receivers, and instrumentation.

RoHS compliant and lead-free, HF Series MLO high pass filters are currently available in five case sizes with varying lengths (6.579 mm ±0.05 mm, and 7.785 mm, 8.674 mm, and 10.198 mm, ±0.254 mm) and fixed widths and heights (3.97 mm and 0.559 mm, ±0.254 mm, respectively), and 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 currently stock to 14 weeks. For more information about AVX’s new HF Series MLO high pass filters, click here.
