About Plextek RFI

Plextek RFI Ltd. is a UK based design house specialising in the design and development of RFICs, MMICs and microwave/mm-wave modules. Formed from Plextek’s RF Integration team, it became a separate line of business within the Plextek Group in November 2012 and a separate limited company in 2015. We have designed over 100 custom ICs at frequencies ranging from baseband to 100GHz and are a third party design house for Wolfspeed (Cree), GCS, Qorvo (TriQuint) and WIN. Our designs are used in a wide range of applications from test instrumentation to infrastructure equipment and the latest mm-wave 5G systems. We are able to draw on a wealth of proven IP to help our clients develop world beating solutions in tight timescales. We have in-house test facilities for both bare die (RF-On-Wafer) and SMT packaged components and are able to undertake the development of mm-wave packaging solutions. Our microwave and mm-wave module development activity encompasses a wide range of technologies including conventional SMT on laminate substrates, High Density Interconnect (HDI), chip and wire, thin film, thick film and LTCC. Plextek RFI is part of the Plextek Group of companies.

Plextek RFI has a dedicated team of first class design engineers with a wealth of commercial experience. A small management team directs the strategy and commercial operation. We focus on technology to provide innovative solutions across a range of markets and applications.
