High Q SMT Filter Family

Dramatic reduction in filter size while maintaining exceptional performance.

Spectrum Control has developed a family of ultra miniature high Q RF filters in surface-mount, BGA packages. Operating from 500 MHz to 10 GHz, these filters are ideal for use in lowpass, highpass, bandpass and diplexer applications.

Overview

Spectrum Control has been a leading provider of high quality, RF filters for A&D applications for more than  40 years. We have applied our RF filtering expertise  to deliver a dramatic reduction in filter size while  delivering exceptional performance. The new MMG series filters deliver high selectivity with low insertion loss and temperature stability in a small form factor with BGA mounting.To achieve this size and performance breakthrough we have employed a novel manufacturing approach using integrated passive devices in glass. This 3D process allows us to build unique solenoid inductor structures that offer superior Q performance compared to other filter technologies, specifically over the 0.5 to 10 GHz frequency range. The wafer-scale process also provides an extremely high correlation between filter simulations and the manufactured product giving us high predictability for custom filters. The performance and quality are also highly consistent, run-to-run.

Performance graph above is typical for allfilters in the MMG family.
