SAW filters now in smaller ceramic packages

3 May 2006 Passive Components

Epcos now offers SAW filters and two-port resonators as SMDs in ceramic packages on quartz substrate with a footprint of 3 x 3 mm. This represents a reduction in area of 40% against the previous package's footprint of 3,8 x 3,8 mm and even 64% for the two-port resonator, which used to measure 5 x 5 mm. Insertion height has also been reduced significantly, from 1,5 to 1,0 mm in the SAW filters and from 1,35 to 1,0 mm in the two-port resonators.

This means that all SAW components for short-range devices are now available in a package with a footprint of 3 x 3 mm.

The filters and resonators are available for the ISM (industrial, medical and scientific) band with centre frequencies of 315, 433,92 and 915 MHz. Despite miniaturisation, typical insertion loss is only 2,4 dB in the passband.

Typical applications include wireless headphones, garage door openers, access control systems, fire alarm systems or remote control systems for cranes or other machines. Due to their rugged hermetically sealed ceramic packages, these filters can be used in ambient temperatures ranging from -40-95°C.
