RF-45 High Frequency Printed Circuit Board: Taconic DK4.5 RF PCB with Immersion Silver
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
Product Overview
Introducing the RF-45 High Frequency Printed Circuit Board, a premium Taconic ORCER PCB designed for optimal performance in RF applications. This board utilizes ceramic-filled PTFE resin laminate with woven fiberglass reinforcement, offering a low loss alternative to traditional FR-4 materials. Key features include:
Dielectric Constant (DK): Stable at 4.5 across varying temperatures.
Dissipation Factor (DF): Consistent performance across frequencies.
Typical Applications
The RF-45 PCB is ideal for a variety of applications, including:
GPS Antennas
RFID Antennas
Satellite Radio Antennas
