30mil AD250C 2-layer RF PCB

Shipped: 5th-April-2024  

1. Introduction of AD250
Rogers AD250C commercial microwave and RF laminate material is designed with a low and tightly controlled dielectric constant of 2.50.
They are built on a cost-effective combination of composite chemistry and construction to yield an uncompromising level of price-performance for today's telecommunication infrastructure.

2. Features
- Rogers AD250C Woven Glass Reinforced PTFE Antenna Grade Laminates
- Dielectric constant of 2.5 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
- Moisture Absorption 0.04%
- CTE in X-axis of 47 ppm/°C, Y-axis of 29 ppm/°C and Z-axix of 196 ppm/°C
3. Benifits
Low loss tangent (<0.002 at 10 GHz)
- Excellent circuit performance in all typical wireless frequency bands
- Higher antenna efficiencies
Controlled dielectric constant (±0.05)
- Repeatable circuit performance
- Ceramic provides higher degree of Dk stability during temperature changes
Very low PIM (-159 dBc at 30 mil, 1900 MHz)
- Excellent antenna performance and reduced yield loss due to PIM related issues
- Low PIM for antenna applications
Excellent dimensional stability
- Repeatable circuit performance and improved manufacturing yields
- Improved plated through-hole (PTH) reliability, compared to typical PTFE based laminates
