What is Rogers RO4350B high frequency PCB?

Rogers RO4350B is a woven-glass reinforced hydrocarbon ceramic laminate built for demanding RF and microwave applications. Unlike standard FR-4, it contains no glass-fiber core variation that degrades high-frequency performance — delivering near-PTFE electrical behavior with the processability of ordinary epoxy/glass.

Manufactured by Rogers Corporation, it is the industry benchmark for power amplifiers, automotive radar, base-station antennas and aerospace phased-array systems where signal loss and impedance stability are critical.

Dielectric constant	3.48 ± 0.05 (stable)	~4.2–4.5 (varies)
Dissipation factor	0.0037 @10 GHz	~0.02 (higher loss)
Moisture absorption	0.06% (lowest)	Higher
Harsh environment	Aerospace / defense ready	Standard switching boards
Cost	Premium material	Economy

Frequently Asked Questions

1.What is Rogers RO4350B used for?

It is used for high-frequency RF and microwave circuits — power amplifiers, automotive radar, base-station antennas, satellite and aerospace phased-array systems where low loss and stable impedance are essential.

2. How is RO4350B different from standard FR-4?

RO4350B has a stable dielectric constant (3.48 ± 0.05), far lower loss (Df 0.0037) and minimal moisture absorption. FR-4 varies in Dk and loses signal integrity at microwave frequencies.

3. What is the typical lead time?

Because we keep Rogers RO4350B laminate in stock, typical delivery is 7–10 days for standard builds. Hybrid or high-layer-count jobs are quoted case by case.
