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.
PCB Case: High Frequency PCB On 1.6mm RO4350B With
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 double sided high frequency PCB built on RO4350B substrate with Tg 280°C
for the application of WiFi Booster. It's 1.60 mm thick without solder mask; Black silkscreen is
directly on the substrate and immersion gold is on pads for soldering. The base material is
used from Rogers Corp., entire board supplying 1 up. They're fabricated per IPC 6012 Class
2 using supplied Gerber data. Each 25 boards are packed for shipment.
