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.
PCB Case: Microwave PCB On 0.762mm RO4350B With
HASL ROHS Compliant
(Printed circuit boards are custom-made products, the picture and parameters shown are just
for reference)
General description
This is a type of microwave PCB built on 0.762mm RO4350B substrate with Tg 280°C for the
application of WiFi Antenna. It's 0.80 mm thick with 2 layers copper, no silkscreen and no solder
mask, HASL Pb free is plated on pads on both sides. The base material is used from Rogers Corp.,
entire board supplying 1 PCB up. They're fabricated per IPC 6012 Class 2 using supplied Gerber
data. Each 25 boards are packed for shipment.
Features and benefits
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;
Heat resistance, chemical resistance, impact strength and peeling strength are good;
Reducing signal loss in high frequency application meets the development needs of communication
technology;
HASL shows excellent wetting during component soldering and it can avoid copper corrosion;
Powerful PCB capabilities support your research and development, sales and marketing;
ISO9001, ISO14001, UL certified manufacturing factory;
On-time service;
More than 15 years of experience;
Application
Transmitter, Power splitter, Microstrip antenna, Splitter module
