Brief Introduction
RO4350B High Frequency Circuit Material is glass reinforced hydrocarbon/ceramic laminates
(Not PTFE) designed for performance sensitive, high volume commercial applications. Currently
Double sided and multilayer RO4350B PCB's are available at Bicheng company. Double sided
RO4350B PCB with thickness 10mil (0.254mm), 20mil (0.508mm), 30mil (0.762mm) and 60mil
(1.524mm) are the bestsellers. We provide prototype runs, small batches and volume production
Services.

Advantages
1) Excellent high frequency performance due to low dielectric tolerance and loss;
2) Excellent dimensional stability.
3) Low thermal coefficient of dielectric constant;
4) Low Z-Axis expansion;
5) Low in-plane expansion coefficient;
6) Stable electrical properties verus frequency;

Applications
1) Attenuator, Automatic gate induction;
2) LNB's for direct broadcast satellites;
3) Microstrip antenna, spread spectrum;
4) Microstrip and cellular base station antennas and power amplifiers;
5) RF identifications tags
6) Spread spectrum communications systems
7) Trunk amplifier, splitter module etc.



PCB Case: High Frequency PCB Spacer with Nothing
on the Substrate
(Printed circuit boards are custom-made products, the picture and parameters shown are
Just for reference)


General description
this is a type of blank high frequency PCB spacer built on RO4350B substrate with Tg 280C
for the application of mixer. It's 1.50 mm thick without solder mask, without silkscreen and
without surface finish.  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. 

Features and benifits
No corrosion in acids, alkali and aqua regia;
Tg > 280;
Stable electrical properties verus frequency;
AOI inspection;
Electrical test and high voltage test;
Impedance control test and solder-ability test;
International approvals;
Great customer service;
Diversified shipping method;


Application
Mixer, Radar data acquisition converter, Radio frequency, RF transceiver
