1. How does raw material sourcing for RF IC design services affect project prices and lead times?
RF IC design service suppliers depend heavily on gallium nitride, silicon germanium, and high-resistivity SOI substrates. China's 2023 export controls on gallium and germanium caused GaN-on-SiC wafer lead times to stretch from 12 to 26 weeks and pushed spot prices up 18%. Design houses with dual-sourced foundry relationships can stabilize project costs, while single-source wafer strategies introduce 20-30% price premiums on rush orders.
