Why Ka-Band Requires PTFE — Not RO4350B
Ka-band spans 26.5–40 GHz. Above 20 GHz, Rogers RO4350B (Df 0.0037) produces ~1.8 dB/cm insertion loss — over a 10cm antenna feed network, 18dB total loss. Rogers RO3003 (Df 0.0010, PTFE ceramic) produces ~0.5 dB/cm — 5dB over the same path. This 3.6× difference in insertion loss is the reason Ka-band PCB requires PTFE substrate, not hydrocarbon ceramic.
| Parameter | RO3003 (Ka-band standard) | RO4350B (below 18GHz only) |
|---|---|---|
| Dissipation factor Df | 0.0010 | 0.0037 |
| Insertion loss at 28GHz | ~0.5 dB/cm | ~1.8 dB/cm — 3.6× higher |
| Process type | PTFE — plasma activation required | Hydrocarbon — FR4-compatible |
| Prototype lead time | 7–10 days (in stock) | 5–7 days |
| Use above 20GHz | ✅ Standard choice | ❌ Not suitable |

Process Capabilities for Ka-Band
- In-house RF plasma activation — mandatory for PTFE, performed on-site within 2 hours of plating
- PTFE-specific drill parameters — 40–60K RPM, prevents hole wall smear that blocks plasma
- Max 2 lamination cycles — enforced for all PTFE materials, Dk stability guaranteed
- Min trace/space 2.5mil / 2.5mil — supports fine Ka-band routing
- Min drill 0.2mm mechanical, 0.1mm laser — via fence down to 0.4mm pitch
- TDR ±10% standard, ±5% available — specify on stackup drawing
- ENIG surface finish standard — flat surface for patch element dimensional accuracy
- IPC Class 3 on request — for defense and satellite programs
