Which RF Applications Suit TF960 PCB? A Dk 9.6 Low-Loss Selection Guide Quick Answer TF960 PCB is a high-frequency laminate made from modified PTFE resin, ceramic fillers, and glass fabric. With a dielectric constant (Dk) of 9.6 ± 0.19 and dissipation factor (Df) of 0.0012 at 10 GHz, it targets RF and microwave circuits requiring low insertion loss and stable impedance. It supports 260°C lead-free...

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...

How to Select 1080 Prepreg for Rogers RO3010 and FR-4 Hybrid Lamination? Introduction Hybrid multilayer PCBs that pair ceramic-filled PTFE high-frequency laminates such as Rogers RO3010 with conventional FR-4 prepreg have become a standard construction for cost-sensitive RF designs. Place the premium high-Dk material only where RF signals travel, and use economical FR-4 bonding sheets elsewhere. Y...

Can One Rogers RO4003C 1100x350mm Double-Sided HF PCB Replace Spliced Antenna Sub-Boards? 1. The short answer Yes. When a single radiating aperture, feed network or sensor array is longer than a standard board and must stay electrically continuous, one Rogers RO4003C 1100x350mm double-sided HF PCB removes the connectors and splices that quietly degrade large antenna designs. It is not the che...

Why Use Tg170 TU-768 FR-4 Cores in a 10-Layer RO4350B Hybrid PCB? When a 10-layer RF module is quoted as a pure ceramic build, the bill of materials can look unreasonable for a volume product. The better engineering response is to ask which layers actually need the high-frequency dielectric. In a 10-layer RO4350B + TU-768 hybrid PCB, the two outer-facing cores use10 mil (0.25 mm) RO4350B hydrocarb...
