State of the Art (SOTA), Inc., has announced a new addition of thin film low pass filters to its high frequency product line. The low pass filters come in a sub-miniature case size and are available on 99 percent alumina substrate constructed using high stability thin film planar technology. Further, 50 ohm terminations are available for either solder of epoxy mounting. These devices feature passband cutoffs at 5.5, 7 and 8 Ghz, maximum rejection greater than 16 dB, and VSWR characteristics of less than 1.4:1, with a insertion loss of less than 0.5 db.
The company's low pass filters were designed to eliminate the need for use of multiple components where space use is critical. They are available in several standard designs and custom cut-off frequencies including high reliability screening. The line is suitable for many different applications to reduce and eliminate unwanted harmonics in telecommunications systems such as satellite receivers, mobile communications, GPS systems, wireless LAN's and WiMAX.
