Low-Loss Transmission and Dielectric Stability of Ceramic PCBs in Satellite and Aerospace Communication Payloads

1. Overview   In satellite and aerospace communication payloads operating above 30 GHz, PCB substrates must maintain exceptional dielectric uniformity and low-loss performance under extreme thermal and radiation conditions.  Ceramic PCB materials—such as alumina (Al₂O₃) and aluminum nitride (AlN)—are widely adopted due to their high dielectric constant, stable dissipation factor, and superior heat conduction.  KKPCB’s...
