A LAMINATE-BASED RF INTEGRATED PASSIVE DEVICE

摘要

Size, cost and performance pressures have driven the industry to ever higher levels of RF integration. Dramatic progress has been made in the integration of the active functions but general adoption of passive integration (integrating functions such as RF filters, diplexers and baluns) has lagged behind. The industry has long sought an organic laminate-based alternative to the LTCC (low temperature co-fired ceramic) solutions that dominate the market. Laminates are a proven, reliable technology, but FR4-based solutions have historically exhibited inferior RF performance and high performance laminates have been too expensive.
