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: 10 Layer RF PCB with RO4350B and FR-4
Combined
(PCB's are custom-made products, the picture and parameters shown are just for reference)


General description
this is a type of high layer count RF PCB built on RO4350B and FR-4 for the application of
Transmitter. It's a 10 layer high frequency PCB board at 1.7 mm thick. It's immersion gold
Finish with red solder mask and white silkscreen. It's fabricated per IPC 6012 Class 2 using
Supplied Gerber data. Each 20 boards are packed for shipment. 


Features and benefits
Good high temperature and low temperature resistance.(-192-260)
Superior corrosion resistance. 
No corrosion in acids, alkali and aqua regia.
SMT process is resistant to reflow soldering, resistant to rework due to gold pads.
Cutting-edge technology
Help you focus on your core competencies on research and development, sales and
Marketing.
1-10 pieces are offered.
International approvals
Great customer service


Application
Preamplifier, WiFi amplifier, Relay Stations, RF transceiver
