AD250C High Frequency PCB

Introduction

Rogers’ AD250C antenna laminates are high-performance, specialty materials designed specifically to meet the needs of today's wireless antenna markets.

These laminates are made from glass-reinforced, PTFE-based materials that offer a controlled dielectric constant, low loss performance, and excellent passive intermodulation (PIM) characteristics. The woven glass reinforcement enhances circuit processability, enabling efficient circuit board production with high yields.

AD250C antenna materials come with options for standard electrodeposited (ED) or reverse treated ED copper foil, allowing for choices that help minimize circuit losses and improve antenna PIM.

Features

AD250C antenna materials offer several notable features:

These materials have an impressively low loss tangent of 0.0013 at 10 GHz and base station frequencies, ensuring minimal signal degradation.

They provide a dielectric constant (Dk) of 2.50, with a tolerance of +/- 0.04, enabling precise control over signal propagation characteristics.

The use of low-profile copper helps to reduce conductive losses, enhancing overall antenna efficiency.

AD250C exhibits very low moisture absorption of 0.04%, ensuring consistent performance and integrity across diverse environmental conditions.

A very high copper peel strength of 14.8 lbs/in ensures reliable adhesion between the copper and the substrate, enhancing the antenna’s durability and performance in challenging applications.

PCB Capability

In terms of PCB capability, we offer a comprehensive range of options for AD250C. Our portfolio includes single-sided boards, double-sided boards, multi-layer boards, and hybrid types.

The standard thicknesses are available, including 20 mils, 30 mils, and 60 mils, allowing flexibility to meet specific requirements.

The finished copper on track lines or pads can be 1oz and 2oz, catering to various conductivity needs.

Our maximum PCB size reaches an impressive size of 400mm by 500mm. This allows for the fabrication of a single board or the inclusion of different designs within a single panel.

At our facility, we provide solder mask options in green, black, blue, red, yellow, and more.

Additionally, we offer various plating for pads, including immersion gold, HASL, immersion silver, immersion tin, OSP, ENEPIG, bare copper or pure gold.

Applications

With its exceptional characteristics, AD250C PCB finds application in a wide range of industries, such as Cellular infrastructure base station antenna, Automotive telematics antenna Systems, and Commercial satellite radio antenna etc.
