Dielectric Uniformity and Manufacturing Precision of PTFE PCBs for Aerospace Communication Equipment

November 12, 2025by kkpcb020

1. Engineering Overview Modern aerospace RF communication equipment, including satellite transceivers and spaceborne antenna modules, demands ultra-low-loss PTFE PCBs with tight dielectric uniformity and precise manufacturing tolerances. Small variations in Dk or CTE can lead to phase drift, impedance mismatch, and degraded link margin in Ku/Ka-band RF payloads. PTFE PCB laminates, with Dk...
