Introduction

Just as its name implies, high frequency is that the frequency is relatively high, generally refers to the frequency of >=300 MHz (i.e. wave length <=1m), that is, the usual radio frequency band. The electromagnetic wave of frequency >=1GHz is called microwave.

 

High frequency printed circuit board or microwave PCB refers to the printed circuit board made on the high frequency (microwave) substrate copper clad plate. The common types are: Double-sided board, multilayer board and mixed structure.


Mixed structure includes high performance special substrate, PP sheet + ordinary performance board and PP sheet mixed pressing board; high frequency substrate + ordinary FR4 substrate; high frequency substrate + metal base etc.

 

Advantages
1) The characteristic of low dielectric loss makes the signal loss at a lower level, which makes the signal transmission of the whole equipment excellent;
2) Low water absorbability influences dielectric constant and dielectric loss less at damp;
3) The temperature coefficient of dielectric constant is among the lowest of any circuit board material, making it ideal for temperature sensitive applications;
4) Stable electrical coefficient of dielectric constant;
5) Superior corrosion resistance;
6) The dielectric constant (DK) is low and stable, so the signal transmission is good without delay;

 

Typical frequencies for wireless applications:
* Current mobile: 0.9GHz - 2GHz
* 3G systems: 2.5GHz
* Bluetooth: 2.5GHz
* GPS: 12.6GHz
* LMDS: 24GHz and 40GHz
* Automotive: 77GHz


Market:

RFID, Wireless communications, base station and antenna, amplifier, military products, consumer electronics.

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.
