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 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.

General description
This is a type of double sided PCB built on 10mil RO4350B substrate with Tg 280°C for the application of 4G Coverage. It's 0.3mm thick finished with white silkscreen over green solder mask and immersion gold are plated on pads. The base material is used from Rogers Corp., entire board supplying 2 up per panel. They're fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 50 panels are packed for shipment.
