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 named microwave.
Typical frequencies for wireless applications:
* Current: 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: Mircowave PCB RO4350B 20 mil (0.508mm)
Green Solder Mask
(Printed circuit boards are custom-made products, the picture and parameters shown are
Just for reference)


General description
this is a type of high frequency PCB built on RO4350B 20 mil substrate for the application
of splitter. It's a 2 layer RF PCB board at 0.6 mm thick. It's copper exposed on top side and
Green solder mask on bottom side. It's fabricated per IPC 6012 Class 2 using supplied Gerber
Data. Each 10 boards are packed for shipment. 


Features and benefits
Excellent dimensional stability.
Heat resistance, chemical resistance, impact strength and peeling strength are good.
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.
Thermal stress test, reliability test, insulation resistance test and ionic contamination test,
High technology
Competitive price
RoHS materials

Application
Uhf radio, Communications relays, LNB, Power divider
