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 Double
Sided Circuit Board
(Printed circuit boards 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 substrate for the application of
multicoupler combiner. It's a 2 layer RF PCB board at 0.6 mm thick. It's copper exposed without
solder mask. It's fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 10 boards
are packed for shipment.
Features and benefits
Tg > 280 ºC
The characteristic of low dielectric loss makes the signal loss at a lower level, which makes
the signal transmission of the whole equipment excellent.
Delamination of copper foil will not be caused by the change of cold and heat due to the
consistency with the thermal expansion coefficient of copper foil.
ENIG has long storage time (It can be stored for more than 1 year in vacuum bag)
High voltage test, Impedance control test, micro-section, solder-ability test,
Make delivery on time keeping 98% on-time-delivery rate.
No MOQ, low cost for prototypes and samples.
Experienced sales persons provide skilled customer services.
UL recognized and RoHS Directive-compliant
Application
Transmitter, Video transmission gear, Low Noise Block, I/O Amplifier
