Unique Properties for High Frequency Applications

Rogers Corporation offers a variety of high frequency laminates designed specifically for use in advanced printed circuit boards (PCBs). Unlike standard FR-4 laminates, Rogers laminates are engineered to have superior electrical performance at high frequencies. Key properties that make Rogers laminates ideal for high frequency PCBs include:

• Low dielectric loss
• Controlled dielectric constant
• Low coefficient of thermal expansion
• High thermal conductivity

Some popular Rogers laminates for high frequency applications include:

Laminate	Dielectric Constant	Loss Tangent	Frequency Range
RO4350B	3.48	0.0031	Up to 20 GHz
RO4003C	3.38	0.0027	Up to 30 GHz
RO4835	3.54	0.0031	Up to 60 GHz

Benefits for Designing Advanced Microwave Circuits

The specialized properties of Rogers laminates provide major benefits when designing advanced microwave and mm-wave circuits:

Precise Impedance Control

The stable dielectric constant facilitates precision impedance control needed for controlled-impedance transmission lines.

Low Loss

The low loss tangent results in less signal attenuation, even at very high frequencies. This improves circuit efficiency and signal integrity.

Excellent Signal-to-Noise Ratio

The low thermal expansion and high thermal conductivity helps minimize microphony noise effects.

FAQ

What types of Rogers laminates are best for 5G applications?

RO4835 and RO4000-series laminates are ideal choices for 5G PCBs operating up to 30+ GHz.

Can Rogers laminates be used for multilayer boards?

Yes, Rogers offers adhesive films that allow bonding multiple laminate layers into a high performance multilayer board.

What is the typical lead time for ordering Rogers laminates?

Lead times vary, but are typically 4-6 weeks. Consult Rogers for their most up-to-date lead time estimate.

Are Rogers laminates expensive?

Although they cost more than standard FR-4, the superior high frequency performance of Rogers laminates makes them well worth the additional cost for advanced microwave and mm-wave PCB designs.
