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: Double Sided Microwave PCB Made On RO4350B
With Immersion Gold Finish
(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 PCB built on high frequency material with Tg 280°C for the application
of preamplifier. It's 1.60 mm thick, white silkscreen over green solder mask on bottom layer. No solder
mask on top layer and immersion gold covering pads on top side. The base material is used from
RogersCorp., 60mil (1.524mm) RO4350B, entire board supplying single up. They're fabricated per
IPC 6012 Class 2 using supplied Gerber data. Each 25 boards are packed for shipment.
