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...

Is a 4-Layer 8mil RO4003C Tg170 FR-4 Hybrid PCB Right for You? Every mixed-signal design eventually reaches the same decision. One section of the board carries RF or microwave traces — antenna feeds, matching networks, a front-end that must hit a defined impedance — while the rest is ordinary power and digital control. The material question follows immediately: all FR-4, all high-frequency laminat...

How Do You Build an 8-Layer RO4350B MT40 Hybrid PCB Without Defects? A hybrid stack looks elegant on a cross-section drawing. It promises the low-loss, tightly controlled RF behavior of a ceramic-loaded hydrocarbon laminate on the outer layers, and the cost and processing familiarity of an FR-4-type low-loss material in the middle. On paper, that is exactly what an 8-Layer RO4350B MT40 Hybrid PCB ...
