High-frequency circuit laminates enable cost-effective antennas

Article Tools

Rogers Corporation’s RO4500 laminates are the latest addition to Rogers' RO4000 product family of high-performance antenna-grade materials. RO4500 glass reinforced hydrocarbon/ceramic laminates provide the controlled dielectric constant, low-loss and passive intermodulation (PIM) response required by wireless infrastructures. Applications include communications cellular base stations and Wi-MAX networks.

RO4500 laminates provide high thermal conductivity and uniform mechanical properties for improved power handling over a broad frequency range. They are fully compatible with conventional epoxy/glass (FR4) circuit board processing techniques. Unlike PTFE antenna solutions, RO4500 laminates do not require special treatment for plated through-hole preparation. The rigid, thermoset laminate can be processed by automated handling systems and scrubbing.
