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: High Frequency PCB RO4350B 20 mil
Immersion Gold
(PCB's 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 for the application of low noise
Amplifier. It's a 2 layer RF PCB board at 0.6 mm thick. It's immersion gold finish with
Green solder mask and white silkscreen from Taiyo. It's fabricated per IPC 6012 Class
2 using supplied Gerber data. Each 10 boards are packed for shipment. 


Features and benefits
No corrosion in acids, alkali and aqua regia.
Tg > 280
the dielectric constant (DK) is low and stable, so the signal transmission is good without
Delay.
ENIG has good oxidation resistance and good heat dissipation.
Whole fabrication process are totally controlled. 
Strict WIP inspection and monitoring as well as working instruction, 
Reduce manufacturing cost from advanced equipment import, worker training and
Technology improvement and management.
1-10 pieces are offered.
Diversified shipping method


Application
RF transmitter, Power divider, LNB, I/O Amplifier
