Passive components and interconnect solutions provider AVX Corp. released two high performance low pass harmonic filters. Based on thin-film multilayer technology, the 512 MHz and 700 MHz low pass filters exhibit low insertion losses (0.9 dB max) and extremely sharp roll-off (-35 dB at 900 MHz). Designed for high frequency wireless applications, including mobile communications systems, military and emergency communications services, and matching networks, the integrated thin-film (ITF) filters offer an ultra-miniature 1206 chip size, and deliver excellent high frequency performance and rugged construction for reliable automatic assembly. The ITF filters are housed in an LGA package.
The 512 MHz and 700 MHz low pass filters offer ultra-miniature 1206 chip size.
Meanwhile, AVX is also planning to extend the frequency range of its high performance ITF filters. Low pass filters covering 300 MHz to 6 GHz are in the works. Measuring just 3.10 mm x 1.60 mm x 0.60 mm (L x W x H ±0.10), the low profile 512 MHz and 700 MHz ITF low pass filters are rated for 3 W continuous power with operating and storage temperatures spanning -40 °C to +85 °C. Offering characteristic impedance of 50 Ω, the harmonic filters feature nickel/lead-free-solder (Sn100) coated terminations compatible with automatic soldering technologies (reflow, wave soldering, vapor phase, and manual). In addition, the RoHS compliant filters are 100% tested for electrical parameters and both visual and mechanical characteristics, and are shipped on tape and reel.
