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 RO4350B 20 mil(0.508mm)
1oz copper
(PCB's 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 RO4350B 20 mil for the application of multiplier.
It's a 2 layer RF PCB board at 0.6 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
RO4003C exhibit a stable dielectric constant over a broad frequency range. This makes it an
ideal substrate for broadband applications.
Reducing signal loss in high frequency application meets the development needs of
communication technology.
Excellent high frequency performance due to low dielectric tolerance and loss.
SMT process is resistant to reflow soldering, resistant to rework due to gold pads.
100% tests inclusive of electrical test and AOI inspection.
