Johanson uses 6/6 RoHS Green Low-Temperature-Co-fired-Ceramic (LTCC) integrated passive
technology in a 4-pin (Sn plated) monolithic structure. This component is 100% RF Tested, making
it a more reliable system, impedance controlled environment, consistent-guaranteed RF
performance in a very small RF front end-solution compared to the L/C discrete solution.
