Brief 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.
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.
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.

for reference)
General description
This is a type of high frequency PCB built on RO4350B 30 mil substrate for the application
of antenna. It's a 2 layer RF PCB board at 0.8 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.
Features and benefits
The dielectric constant (DK) is low and stable, so the signal transmission is good without delay.
Delamination of copper foil will not be caused by the change of cold and heat due to the
consistency with the thermal expansion coefficient of copper foil.
Low water absorbability influences dielectric constant and dielectric loss less at damp.
SMT process is resistant to reflow soldering, resistant to rework due to gold pads.
Meeting your printed circuit board needs from PCB prototyping to mass volume production.
Engineering design prevents problems from occurring in pre production.
