At Highleap Electronics, we specialize in the manufacturing of RF (Radio Frequency) and Microwave PCBs designed to support signal frequencies from 100MHz up to 30GHz and beyond. These advanced circuit boards are engineered to meet the stringent electrical and thermal requirements of high-frequency communication systems.
RF PCBs typically operate above 100MHz, while Microwave PCBs handle signals above 2GHz. Both are critical in today’s wireless and high-speed systems, including cellular infrastructure, satellite communications, radar systems, GPS modules, automotive radar, and medical imaging.
With years of experience and access to top-tier RF materials like Rogers, Taconic, and Isola, we provide reliable, high-performance PCB solutions with tight impedance control and minimal signal loss—whether you’re developing a prototype or scaling to volume production.
Each RF and microwave PCB project requires a tailored approach to meet the demands of high-frequency signal transmission. At Highleap Electronics, we leverage cutting-edge fabrication technologies and strict process control to ensure signal integrity, low insertion loss, and consistent impedance across all frequency ranges.
Whether you’re working with multi-layer hybrid stackups, complex cavity structures, or mixed-material designs, our engineering team delivers customized PCB solutions that meet both functional and performance goals. The boards shown below are just a few examples of our capabilities in delivering high-frequency circuit boards for applications ranging from radar and satellite to 5G base stations and RF amplifiers.
Highleap provides free one-on-one engineering support and DFX to RF and microwave PCBs projects.
In essence, an electronic signal is a quantity that varies over time and communicates some kind of information. The quantity that varies is usually voltage or current. These signals are passed between devices as a way to send and receive information, like audio, video or encoded data. While these signals are often transmitted through wires, they can also be passed through the air by radio frequency, or RF, waves.
These radio frequency waves vary between 3 kHz and 300 GHz, but they are subdivided into smaller categories for the sake of practicality. These categories include the following:
These are the signals handled by most traditional analog components, and they include signals with frequencies up to 50 MHz.
RF signals cover a wide frequency range, but in circuit design, they usually refer to frequencies from 50 MHz to 1 GHz, which are also used in AM/FM transmission.
Microwave signals have frequencies above 1 GHz, up to around 30 GHz. They are used for cooking in microwave ovens and high-bandwidth signal communication.
RF and microwave PCBs are typically built using advanced composites with very specific characteristics for dielectric constant (Er), loss tangent, and coefficient of thermal expansion (CTE).
The materials used in microwave PCB materials typically consist of a combination of PTFE, ceramics, hydrocarbon, and various forms of glass. The choice of material depends on factors such as quality, cost, ease of manufacturing, electrical performance, thermal robustness, and resistance to moisture.
PTFE with microglass fiber or woven glass is often preferred. This material offers excellent electrical properties but may come at a higher cost. If budget constraints exist while maintaining high quality, ceramic-filled PTFE is a suitable alternative that provides good performance while being easier to manufacture, thereby reducing costs.
Ceramic filled with hydrocarbon is even more cost-effective to produce, but it may result in a slight decrease in signal reliability compared to other options.
Thermal robustness is crucial for applications exposed to soldering stresses, demanding drill scenarios in multilayer boards, or thermally challenging environments like aerospace. PTFE with microglass fiber or woven glass has excellent electrical properties but a high coefficient of thermal expansion (CTE). On the other hand, ceramic-filled PTFE offers great electrical characteristics and a low CTE, making it a thermally tougher choice. Ceramic-filled hydrocarbon sacrifices some electrical performance but maintains a very low CTE.
Moisture absorption is important to consider. PTFE ceramic has a lower rate of absorption, but adding woven glass can increase it. However, incorporating hydrocarbon in PTFE ceramic leads to a smaller increase in absorption, providing a balanced choice between cost and resistance to wet environments.

To ensure optimal performance of RF and microwave PCBs, it is important to follow certain design considerations. For more details on RF PCB design, visit our microwave PCB design guidelines.
When designing an RF and microwave PCBs, digital designers should Carefully place RF components on the PCB to minimize signal loss and interference. Group related components together to reduce trace lengths and improve signal integrity.
Implement a solid grounding scheme to provide a low impedance return path for RF signals and minimize noise. Separate digital and RF ground planes to prevent interference.
Use controlled impedance transmission lines to maintain signal integrity. Match the characteristic impedance of the transmission lines with the source and load impedance to minimize signal reflections.
Keep RF and microwave PCBs traces as short and direct as possible to minimize signal loss and interference. Use wide traces to reduce resistance and inductance.
Implement proper decoupling capacitors near RF components to suppress noise and provide stable power supply. Place sensitive analog components away from noise sources such as switching regulators or high-speed digital circuits.
Choose an appropriate RF and microwave PCBs stack-up that provides sufficient isolation and controlled impedance for RF and microwave signals. Consider using dedicated RF layers and separate power and ground planes.
Incorporate proper shielding techniques such as ground planes, shielding cans, or RF shielding materials to prevent electromagnetic interference.
Consider the heat dissipation requirements of RF components and ensure proper thermal management to avoid signal degradation due to temperature variations.
