Modern printed circuit boards (PCBs) implement several unique technologies to increase their performance and capabilities. One part of the PCB market that is rapidly developing is the use of radio frequency (RF) technology. With many well-known manufacturers scurrying to produce the best-in-class RF PCBs, their demand will likely continue to grow. In this blog, we will discuss what RF technology is and how it is being implemented on modern PCBs.
RF PCBs are specialty circuit boards that can communicate in the radio and microwave frequency range. In particular, radio frequency boards typically operate between 500 MHz to 2 GHz, while boards that are compatible with frequencies over 2 GHz are considered microwave. Compared to regular PCBs, RF and microwave boards have a particularly complex architecture and are thus more difficult to design. This is mostly due to the increased noise sensitivity and strict impedance tolerances that come with transmitting or receiving radio signals.
One of the most salient characteristics that determine the success or failure of an RF or Microwave PCB is the materials used in the manufacturing process. Choosing materials becomes a delicate interplay between intended application and budget since higher quality materials can be much more expensive than lesser quality ones. The quality of the selected material is determined by some unique properties:
RF boards are being implemented in a variety of communication applications, including smartphones, sensors, security, and more. In wireless technologies, such as remote controls, there are generally two paired PCBs that communicate in the RF range. Additionally, newer smartphones that are compatible with 5G technology are mostly dependent on RF PCBs to operate efficiently. Alternatively, microwave PCBs are typically reserved for high-fidelity communication systems such as those found in satellites and navigational systems. Regardless of the application, it is important to source your RF PCBs from a reputable distributor.
