Today we are a technology leader in radio frequency (RF) filtering serving customers rapidly and flexibly across the globe, but like many successful technology companies we started out with little more than an idea. For us this idea is smaller, lighter and smarter solutions that make our customers more competitive.?

With locations in the Europe (Helsinki, Oulu, Stockholm) and China (Zhongshan, HQ) we have come a long way from our humble beginnings with the RF filter service business in Naples, Florida that we started in 2007.
