Brief Introduction
with the development of electronic communication technology, the communication frequency
Is becoming higher and higher, and the high frequency signal transmission, need to use low
Dielectric constant (Dk), low dielectric loss (Df) but expensive special materials. these materials
Have cyanate and high frequency materials such as polytetrafluoroethylene / ceramic based
Materials (PTFE/Ceramic), hydrocarbons / ceramic based materials (Hydra Carbon/Ceramic).
Usually these materials are expensive. 
Reducing the cost is an important means for customers to improve the competitiveness of
Products. Therefore, the customers adopt the laminated structure of mixed materials in the
Design of PCB structure, that is, the necessary signal layer uses high-frequency materials to
Meet the needs of signal transmission. Other line layers are made of conventional fiberglass
Epoxy FR-4, which we call a hybrid board.

General description
this is a type of high frequency PCB built on RO4003C and FR-4 combined for the application
of RF transceiver. It's a 4 layer RF PCB board at 1.0 mm thick. It's immersion gold finish with
Green solder mask and white silkscreen. It's fabricated per IPC 6012 Class 2 using supplied
Gerber data. Each 10 boards are packed for shipment.
