PRFI is a UK based design house specialising in the design and development of RFICs, MMICs and microwave & mmWave modules. We have designed over 100 custom ICs at frequencies ranging from baseband to 100GHz and are a third party design house for GCS, Qorvo, WIN and Wolfspeed. Our designs are used in a wide range of applications from test instrumentation to infrastructure equipment and high volume consumer wireless devices including mmWave 5G. We have in-house test facilities for both bare die (RFOW) and SMT packaged components. 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.
