A High-Frequency PCB Requires the Use of Specialized Materials & RF PCB Fabrication

Special materials are required to achieve the high frequency provided by this type of printed circuit board – any changes in the ER value of these materials can affect the impedance of the board. Many PCB designers turn to Rogers dielectric material for its lower dielectric loss, reduced signal loss, lower cost of circuit fabrication, and better suitability for fast-turnaround prototyping applications.

Apart from choosing the appropriate PCB material and determining the correct value of the ER, designers should take parameters such as conductor width and spacing, substrate constant into consideration. These parameters must be exactly specified and implemented with the highest level of process control.

Unitepcb is a High-Frequency PCB Manufacturer, superior-performing high-frequency PCB, radio frequency PCB fabrication, and Microwave PCB fabrication services. We manufacture high-frequency PCBs with frequency typically in the range from 500MHz to 2GHz. The following table shows some of our common-use materials for High-Frequency PCBs manufacturing.

High Frequency PCB

Benefits of High-Frequency PCB

A high-frequency circuit board is known for its quick signal flow rates as also its frequency range of up to 100 GHz. Some of the characteristics of High-Frequency PCBs include:

• The dissipation factor of High-Frequency PCBs is typically between 0.0019 and 0.025. This means that the signal transmission rate isn’t impacted and that signal transmission loss is minimized.
• Once again on account of a low dielectric constant there is less signal delay and also higher rate of frequency emission.
• High-Frequency PCBs are known for their high chemical resistance. This makes them less susceptible to corrosion.
• With its low moisture absorption such boards are ideally suited for use in humid environments.
• With low dimensional stability, such PCBs are suited to be used in environments with high temperatures.

Some of the other advantages of high-frequency circuit boards offer, include:

• They enable designers to achieve improved signals, and high functional density in small size and at reduced costs.
• They are also provided with ground plane and help reduce emissions of electromagnetic waves and maintain signal quality.

Applications of High-Frequency PCB

High-frequency PCBs find their requirement in radio frequency, microwave, mobile, and satellite applications. With the increasing complexity of electronic circuits and fast data transmission rates, high-frequency PCBs are the preferred choice for developing products.

1. Advanced communication systems in industrial, medical, and defense applications requires high-frequency PCB.
2. High-frequency PCBs are a perfect choice for satellites, airborne, and ground-based radar systems.
3. Cell phones, GPS receivers, and RF remote control use high-frequency PCBs for better signal transmission.


Microwave PCB & Radio frequency PCB(RF PCB) definition

Microwave PCB

The PCB industry defines an RF circuit board as any high-frequency PCB operating above 100MHz.
Anything above 2GHz in the radio frequency class is a microwave PCB.

Radio Frequency PCB(RF PCB)

The radio frequency at which they operate is the main difference between RF Circuit Boards and Microwave PCB. Microwave PCB can be classified as any RF circuit board operating at or above 2GHz.

Microwave PCBs and RF Boards in Common

Radio-frequency circuit boards and microwave PCBs are needed to transmit and receive radio signals. Some common applications include radar installations and cell phones.

Common Problems and Solutions for Microwave PCB and RF Circuits Board

Microwave PCB and RF circuit boards are more difficult than traditional PCB layouts. Because of the potential problems in transmitting and receiving radio signals, this is a problem. Noise sensitivity and tighter tolerances for impedance are two of the most significant problems.

Radio and microwave signals have a much higher level of noise sensitivity than traditional circuit boards and require tighter impedance tolerances. Ground plans are the best way to solve these problems. These solutions will allow the RF/Microwave PCB to have the best performance.

Applications for RF Boards

There are many applications for RF boards, such as wireless technology, sensors, robotics, security, and smart phones. With technological innovation, the demand for RF boards is increasing in the future.

It is crucial to find a competent RF PCB manufacturer or Microwave PCB factory to ensure that the boards are manufactured to high-quality standards. Our reputation speaks for us. We are known for bringing the most complex layout ideas to life.
