Surface Mount MEMS microphones :: Knowles

Surface Mount MEMS Microphones

  • New MaxRF models eliminate GSM/TDMA burst noise and provide wide-band RF noise suppression
  • UltraMini footprint - less than 11.5mm
  • Slim UltraMini footprint - less than 8.5mm
  • Digital mics eliminate analog noise
  • Integrated designs with differential or switchable gain
  • "Zero height" for thinnest ever designs

Built on our CMOS/MEMS technology platform (originally launched in 2002), the SiSonic™ silicon-based microphone series is entering its fourth generation of development, with product shipments exceeding 1 billion units to date. The proven and evolving design series continues to support high-performance, high-density innovation in such applications as cell phones, digital still cameras, portable music players, and other portable electronic devices.

Design variables include ever-smaller sizes, lower profiles and mounting options, increased output capacities, and new digital audio options that eliminate analog noise. For manufacturers, surface mount designs eliminate off-line subassembly production costs. Customized designs are supplied on tape-and-reel and can be run through standard automatic pick-n-place equipment during in-line surface mount manufacturing.

The microphones can also be integrated with our patented IntelliSonic™ software and special porting designs to provide a precisely customized sound.
