Introduction:
RF PCB introduction:
RF is Radio Frequency, referring to the radio, a high-frequency signal.
For performance index of PCB, it can be an ordinary FR4 epoxy glass fiber and also Teflon and other dedicated microwave substrates.
RF board standards:
1,In the design of miniwatt RF PCB, main material is standard FR4 (Good insulation characteristics
uniform material, dielectric constant ε = 4,10%).
2,In the RF PCB, every component should compact configuration to ensure that the shortest connection
between the every component.
3, For a mixed-signal PCB, RF and analog section should stay away from digital part
(This distance is usually more than 2cm, at least 1cm), the digital part of the ground should be
separated from the RF part.
4, To choose the components working in high frequency environment should use of surface-mount component as far as possible. Because the surface-mount component is small volume generally and the pin of component is very short.

Introduction:
The increasing complexity of electronic components and switches continually requires faster
signal flow rates, and thus higher transmission frequencies. Because of short pulse rise times
in electronic components, it has also become necessary for high frequency (HF) technology to
view conductor widths as an electronic component.
Depending on various parameters, HF signals are reflected on circuit board, meaning that the
impedance (dynamic resistance) varies with respect to the sending component. To prevent such
capacitive effects, all parameters must be exactly specified, and implemented with the highest level
of process control.
Critical for the impedances in high frequency circuit boards are principally the conductor trace
geometry,the layer buildup, and the dielectric constant (er) of the materials used.
Specification:
High frequency pcb high-performance insulating material for microwave, radio frequency (RF) and high-speed digital signal processing (DSP) market with PTFE/type woven glass fiber fabric sheet.This material can be applied to LNAs LNBs, PCS/PCN antenna system, global positioning system (GPS) and UMTS antenna system,And the power amplifier, passive components, collision avoidance radar system, aviation help guide remote control technology and system of the phased array radar.
High frequency materials are UL 94V-0 rated for active devices and high power RF designs.
High-frequency circuit board includes a hollow core plate provided with grooves and glue to flow through the upper and lower surfaces of the CCL on the core plate, the upper opening of the hollow groove and a lower opening edge with a wall.
