TP1020 2-Layer High-Frequency PCB for Aerospace & Defense Applications
1.Introduction
TP series represents a breakthrough in high-frequency thermoplastic materials, combining ceramic fillers and polyphenylene oxide (PPO) resin without fiberglass reinforcement. The TP1020 variant offers a precisely tunable dielectric constant (10.2±0.2) with exceptional stability across frequencies.
Engineered for mission-critical RF systems, TP1020 laminates feature:
Adjustable Dk (3–25 range) via ceramic/PPO ratio
Ultra-Low Loss (0.0012 @10GHz)
Glass-free construction for consistent electrical performance
ENIG surface finish for reliable solderability
Ideal for global satellite navigation, missile guidance, and compact antennas requiring millimeter-wave precision.
