High-Frequency PCB Manufacturer | Custom RF & Microwave Boards

Why choose HXD's High Frequency PCBs?

HXD has many years of experience in manufacturing high frequency PCB. We have the following technical advantages in design and manufacturing:

1. HXD can support the customer to check precise design of conductor geometry and layer stackup. By this way, it can ensure strict impedance control, guaranteeing signal integrity and transmission stability.

2.HXD produces such boards with high-precision manufacturing processes. HXD is capable of producing microvias and multilayer impedance-controlled boards. Depending on board stackup, we offer technical treatments such as backdrilling to ensure signal integrity.

3. HXD have different high-frequency materials and can make hybrid PCB (such as Rogers + FR4 hybrid layers). It can achieve a balance between high performance and cost. According to customer needs, we can choose different thicknesses and dielectric to meet various high-frequency applications.

Materials Types Used in High-Frequency PCB

High-frequency materials must possess these key characteristics: low dielectric constant, low loss factor, and good thermal stability. Rogers, Dupont, Taconic, Isola, and Panasonic are main materials. HXD always keeps a long-term stock of high-frequency substrates such as Rogers (4350B, 4003C), Taconic, and Isola.

Sometimes, to balance performance and cost, we also use a combination of high-frequency materials and standard FR4 in a stackup. Normally low-loss materials are used in the high-frequency layers while standard FR4 materials in other layers. By this way, It can optimize the signal performance and manufacturing costs.

Based on HXD’s years of manufacturing experience and the application scenarios, we have sorted out a clear guide for high-frequency PCB materials for your reference:

Application	Material	Comment
≤1 GHz	FR4	Suitable for low-speed signals or cost-sensitive high-frequency boards; can meet some high-frequency applications through optimized layer stack-up, but performance degrades as signal speed exceeds 1.6 GHz.
1–5 GHz	Rogers 4350B / 4003C	Low Dk and low Df make it suitable for high-speed digital circuits and RF modules, ensuring stable impedance and signal integrity.
>5 GHz	PTFE (Teflon), Rogers RO3003 / RO3006	It features a low dielectric constant and low loss, making it suitable for microwave circuits, satellite communications, and antenna modules; FR4 is not suitable at high frequencies.
Above GHz / High Speed	Panasonic Megtron 6	Low Dk and low Df, with stable thermal characteristics, suitable for high-speed digital and radio frequency signal transmission.
Hybrid	High Frequency Core + FR4 Prepreg	Use low-loss materials in high-frequency layers and FR4 in non-critical layers; this approach balances performance and manufacturing costs.
Flex	PTFE, Kapton	Suitable for applications requiring high-frequency signal transmission and flexible bending capabilities, such as RF modules and wearable devices.

Advantages of High-Frequency PCBs

Excellent Signal Integrity

HXD’s High Frequency PCBs use materials with low and stable dielectric constants. It can significantly reduce signal transmission delay. At the same time, high-frequency materials offer higher processing precision, effectively reducing signal reflection and crosstalk, ensuring signal accuracy and consistency during high-speed data transmission.

Extremely Low Signal Loss

HF materials (such as PTFE and Rogers series) have extremely low loss factors. In the result, there is very little signal attenuation during transmission. It is very crucial for long-distance communication, radar systems, and high-frequency radio frequency applications.

Excellent Thermal Management and Physical Stability

High-frequency material have excellent dimensional stability. So even under drastic temperature changes,vias and traces are less prone to cracking due to thermal expansion and contraction.What’s more, many high-frequency materials have better heat dissipation performance. It can effectively protect valuable RF chips. Their extremely low water absorption rate also allows the PCB to maintain stable and reliable electrical performance in humid or harsh environments.
