Microwave
and RF PCB Built on Rogers 20mil 30mil 60mil AD250C Antenna Material With
Dielectric Constant (DK) of 2.50
(Printed
Circuit Boards are custom-made products, the picture and parameters shown are
just for reference)
General
Description
Rogers
AD250C antenna PCBs are PTFE based with woven fiberglass and micro-dispersed
ceramic filled composites that provide controlled dielectric constant (2.50
+/-0.04), low loss (0.0014 loss tangent at 10GHz) and low passive
intermodulation (PIM) performance which is good for antenna applications. Among Rogers antenna grade materials, they are a type of cost-effective high
frequency PCB for today's telecommunication infrastructure, combining chemistry
composites and design of build-up structure.
