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 Speed PCB Boards Built On RO4350B 10 mil 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
10 mil substrate for the application of antenna. It's a 2 layer RF
PCB board at 0.3 mm thick. It's immersion gold finish without
solder mask. It's fabricated per IPC 6012 Class 2 using supplied
Gerber data. Each 50 boards are packed for shipment.
Features and benefits
Low water absorbability influences dielectric constant and
dielectric loss less at damp.
Tg > 280 ℃
Good high temperature and low temperature resistance.(-192℃-260℃)
Gold has high solderability, no stressing of circuit boards and
less contamination of PCB surface.
High voltage test, Impedance control test, micro-section,
solder-ability test,
PCB manufacturing is strictly as per required specifications.
Eligible products rate of first production: >95%
No MOQ, low cost for prototypes and samples.
International approvals
Application
Low noise amplifier, Optical coupler, RF Switches, Automatic gate
induction
