Dk 3.0 or Dk 10.2: Which High-Frequency Substrate Fits Your Antenna Design? Quick Answer Choose Dk 3.0 for wider traces, easier impedance control, and higher-frequency operation where dispersion matters. Choose Dk 10.2 for circuit miniaturization, compact antenna spacing, or high-Dk architectures. TFA1020, a PTFE-ceramic composite with no glass fiber, delivers Dk 10.2 at 10 GHz with Df as low as 0...

Why Choose a 4-Layer 5mil RT6202+FR-4 Hybrid PCB for High-Frequency RF Designs? Introduction When designing RF and microwave circuits above 3 GHz, engineers face a persistent dilemma: standard FR-4 substrates introduce unacceptable signal loss and dielectric instability, while fully Rogers-based multilayer boards carry prohibitive material costs for digital and power sections. A 4-layer 5mil RT620...
