AD255C High Frequency PCB 2-Layer 20 mil

Shipped: 4th-MAR-2024  

1. Introduction of AD255C
The AD255C antenna laminates are glass-reinforced, PTFE based materials that provide controlled dielectric constant, low loss performance, and very good passive intermodulation (PIM) performance. The woven glass reinforcement affords good circuit processability and enables high yield circuit board fabrication.

 
AD255C materials are offered with standard electrodeposited (ED) or reverse treated ED copper foil options. This provides choices that are
sufficient to help reduce both circuit losses and antenna PIM. Stability of PTFE over wide frequency and temperature ranges, with low loss properties, makes AD255C laminates ideal for a variety of microwave and RF applications in telecommunication infrastructure.
 
2. Features
- Very low loss PTFE and ceramic filled composite
- Dielectric constant of 2.55 with tight tolerance at 10 GHz/23°C
- 0.0013 loss tangent at 10GHz and base station frequencies at 10 GHz/23°C
- Decomposition Temperature (Td) >500°C
- Low profile copper
- Moisture Absorption 0.03%
- CTE in X-axis of 34 ppm/°C, Y-axis of 26ppm/°C and Z-axix of 196ppm/°C
3. Benefits
- Lower insertion loss
- Low PIM for antenna applications
- Phase stability due to excellent TCEr
- Compatible with the processing used for standard PTFE based PCB substrates
