Creowave Filters Oy

Creowave Oy, the predecessor to Creowave Filters Oy, was founded in 2004. Creowave Oy specialised in the oil and gas industry but launched the RF filter business just a year after the company was founded.

In 2005, a major telecommunications company approached Creowave Oy to develop measurement filters for their base station testing, marking the beginning of the filter business. Over the years, the company’s reputation has grown, leading to an expansion of its customer base.

Creowave answered the call for low PIM filters around 2009 and started determinedly to design and produce them for testing purposes. The decision to focus firmly on PIM measurement filters was a good one. After some challenging years, the decision started to bear fruit and eventually Creowave became known as a prompt and high-quality PIM filter producer among leading mobile base station manufacturers.

A rapid increase in the number of mobile network users and the need for higher and higher transfer capacity put immense pressure particularly on mobile base station manufacturers. Passive intermodulation (PIM) measurement gives a good view on base station build quality and especially the purity of the transferred spectrum. Low PIM performance causes degradation in base stations’ capacity. The first requirement in PIM performance evaluation is to have a test bench that offers good and solid PIM performance.

In October 2013, the filter business was spun off into its own entity, Creowave Filters Oy. Since then, the focus has been on maintaining existing customers and acquiring new ones, particularly from Western military and defence companies.

In 2019, DA-Design Oy acquired Creowave Filters Oy, making it a part of the DA-Group.
