• Surface Mount Transformers
  • Surface Mount Couplers
  • Surface Mount Splitters



MiniRF's passive component product line was originally developed by PDI (Premier Devices Inc). PDI was acquired by Sirenza Microdevices and Sirenza by RFMD. RFMD decided to exit the passive components business and MiniRF was born.

MiniRF's product line includes transformers, couplers, splitters, mixers and chokes.  A ferrite core is found in almost every MiniRF product. The performance of MiniRF's product depends on the magnetic properties of the core and how it interacts with the wire wrapped around it. Winding cores is a manual process and therefore labor intensive. RF performance can change with minor differences in how the wire is wound to the core, so careful attention to detail is required from sourcing materials all the way through manufacturing and test.
