History & Mission


Wainwright Instruments GmbH was founded in 1979 in Germany by Claire R. Wainwright – a pioneer in the US filter industry – and his wife Christel. Since then we have been designing and manufacturing low pass, high pass, band pass, band reject and notch filters, manually and digitally tunable filters, as well as diplexers, duplexers, triplexers, multiplexers, monoplexers and absorptive filters.

Among others we specialize on L/C, Cavity and Helical designs. We offer many standard filters with guaranteed specifications, listed prices and fast delivery times, but we also welcome inquiries for filters built to your specific needs.

Since Claire passed away in 2007, his well trained crew – led by our technical director Wolfgang Heine – has continued to improve on his designs and has added many new models. Claire and Christel’s son Terry joined the company in 2009 and became managing director in 2011. Prior to joining the company Terry worked for 15 years as a fund manager, predominantly based in Asia.

In 2012 we invested in a new company building, quadrupling our floor space and giving us room for further developments and growth.
