Precision-Engineered Multi-Layer RF Circuit Board for High-Frequency Applications
Achieve superior signal integrity and thermal reliability with PCBSync’s RO4500 14-layer complex RF system PCB — purpose-built for demanding high-frequency, mixed-signal, and radar applications where performance is non-negotiable.
Product Overview
This advanced 14-layer PCB is fabricated on Rogers RO4500 series laminate, a thermoset material specifically formulated for complex multilayer RF designs. With a finished board thickness of 2.0mm, 2oz copper weight, and a hard gold surface finish, this board delivers the electrical performance, mechanical durability, and connector reliability that mission-critical RF systems demand.
Rogers RO4500 offers a stable dielectric constant across a wide frequency range, low insertion loss, and excellent compatibility with standard FR-4 fabrication processes — making it the ideal substrate choice when your design requires RF-grade performance without exotic manufacturing constraints.
Key Specifications
- Material: Rogers RO4500 Series (Hydrocarbon/Ceramic Thermoset)
- Layer Count: 14 Layers
- Board Thickness: 2.0mm
- Copper Weight: 2oz (70µm) finished
- Surface Finish: Hard Gold (Electrolytic Nickel/Gold)
- Application Class: Complex RF / Microwave Systems
Why Choose This PCB?
Exceptional RF Performance Rogers RO4500 maintains a tightly controlled dielectric constant (Er) with minimal variation over frequency and temperature. This ensures consistent impedance matching, predictable transmission line behavior, and low-loss signal propagation across your entire operating bandwidth — critical for applications spanning L-band through Ka-band.
14-Layer Stackup Versatility A 14-layer construction supports complex routing architectures, including dedicated RF signal layers, stripline and microstrip configurations, embedded power/ground planes for shielding, and separate digital/analog routing zones. This stackup density is ideal for integrated transceiver modules, phased array feeds, and multi-function RF assemblies.
2oz Copper for Power and Thermal Management Heavy 2oz copper on all layers provides lower DC resistance, improved current-carrying capacity, and enhanced thermal dissipation — essential in power amplifier stages, high-duty-cycle radar transmitters, and densely packed RF front-end modules.
Hard Gold Finish for Maximum Durability The electrolytic hard gold surface finish delivers outstanding wear resistance for edge connectors, press-fit contacts, and high-insertion-cycle interfaces. Unlike ENIG or immersion finishes, hard gold withstands repeated mating cycles without degradation, ensuring long-term connection reliability in field-deployed systems.
Ideal Applications
- Radar and electronic warfare (EW) systems
- Satellite communication (SATCOM) modules
- 5G mmWave infrastructure and antenna systems
- Aerospace and defense RF assemblies
- Software-defined radio (SDR) platforms
- Point-to-point microwave backhaul
- Medical RF imaging equipment
