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 TACONIC TLA-6 37 mil
1oz Immersion Gold.
(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 TLA-6 37 mil substrate for the application
of GPS antenna. It's a 2 layer RF PCB board at 1.1 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
Superior corrosion resistance. 
Tg > 280
the dielectric constant (DK) is low and stable, so the signal transmission is good without
Delay.
ENIG has long storage time ( It can be stored for more than 1 year in vacuum bag)
UL, ISO certified PCB manufacturing factory.
Thermal stress test, reliability test, insulation resistance test and ionic contamination test,
More than 15 years' experience
Fast and flexible to save the time of production from prototype to standard production
Diversified shipping method


Application
Balanced mixer, Transmitter combiner, Power amplifier, 4G antenna
