AVX Corporation introduced new 0805-case BP Series multilayer, integrated thin film (ITF) band-pass filters. Designed for broad compatibility with a wide range of high-frequency wireless applications, including mobile communications systems, satellite TV receivers, GPSs, vehicle-locating systems, and wireless LANs, the series is available in five frequency bands spanning 1,308MHz to 4,320MHz with 50Ω characteristic impedance, and is rated for 5W continuous power, and operating temperatures spanning -40°C to +85°C. The new surface-mount band-pass filters also exhibit low insertion loss and sharp roll-off, delivering excellent high-frequency performance in an ultraminiature, low-profile case measuring just 2.03mm x 1.55mm x 0.8mm (±0.1mm), and are ruggedly constructed and packaged on tape and reel for reliable automatic assembly.

“Our new high-performance, integrated thin-film band-pass filters provide wireless systems engineers with peak performance and quality in an ultraminiature 0805 chip size especially designed for the smaller and more crowded PCBs that next-generation wireless electronics are based on,” said Larry Eisenberger, principal technical marketing engineer at AVX. “Initial releases have been well received, and plans to extend this range of high-performance filters to cover the 1–5GHz range are already in the works.”

The new ultraminiature BP0805 Series ITF band-pass filters are available in five frequency values designed for use in five frequency bands: 1,308MHz for 1,220–1,420MHz; 1,457MHz for 1,447–1,467MHz; 1,795MHz for 1,785–1,805MHz; 2,160MHz for 1,960–2,360MHz, and 4,320MHz for 4120–4520MHz. They have nickel/lead-free-solder coated (Sn100) terminations compatible with reflow, wave, vapor phase, and manual soldering technologies, are RoHS compliant, and are 100% tested for electrical parameters and both visual and mechanical characteristics.
