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: High Speed PCB Boards Built On RO4350B 10 mil With Immersion Gold
(Printed circuit boards are custom-made products, the picture and parameters shown are just for reference)
This is a type of double sided high frequency PCB built on RO4350B 10 mil substrate for the application of antenna. It's a 2 layer RF PCB board at 0.3 mm thick. It's immersion gold finish without solder mask. It's fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 50 boards are packed for shipment.
