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.

Features and benefits
the dielectric constant (DK) is low and stable, so the signal transmission is good without
Delay;
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;
RO4350B exhibits a stable dielectric constant over a broad frequency range. this makes
It an ideal substrate for broadband applications;
Engineering design prevents problems from occurring in preproduction;
Eligible products rate of first production: >95%  
No minimum order quantity and low cost sample;
on-time service;
More than 15 years of PCB experience;


Application
TV antenna, Directional coupler, Relay Stations, Automatic gate induction
