The AC coupling system, the rate at which data can be transferred depend on how great signals can express variant relations. And furthermore, the electromagnetic wave is the precise reposition of the AC component of the original signal. So time-varying repetitive current generates electromagnetic field whether you are rewinding to or not. EMR is a natural extension of electric signal using wireless circuit. In other words, why does wireless almost always refer to RF or RF technology? Why various other phenomena like what I just now described can transfer information wirelessly? There are a few reasons. So now let’s return to the question of why electromagnetic wave, its base system is so common compared to other forms of wireless communication. So now why RF technology is important for wireless communication? So, to understand this, I want to bring the importance, to recognize that electromagnetic radiation is unique in its ability to extend electro circuitry into the wireless domain, so anything that can travel to a non-conducting material, mechanic motion, soundwave and even heat, could be used as a means of converting electric energy into information and does not rely on conductive interconnection. The description of this knowledge was set down by James Clerk Maxwell with a set of four equations that bear his name. ![]() So RF technology is of knowledge that describes laws of physics that are applied to the generation, conversion, propagation and detection of electromagnetic waves. When it comes to RF, or radio frequency technology, you are talking about wireless electromagnetic signal that is used as a form of communication in wireless electronics. Radio frequency propagation occurs at the same speed of light and can travel in the absence of any medium, like air. They are above the hearing range of human ear, about 20 KHz and extend to just below the infrared region of light, so about 300 GHz. Radio frequency, which refers to radio wave, a destination for electromagnetic wave. So let us understand first what RF means. I would like to explain RF technology in this way. ![]() Explain what RF technology is and why it’s important.Ī: Okay, I will try to explain this. So Amos, let’s just start off at the most basic level. We are excited to get your insights on the show today. ![]() Amos, thanks for joining me.Īmos(A): Yeah, thanks for asking me to join the podcast. He is the senior manager of R&D and product development engineering at TE Connectivity. Joining me for the conversation today is Amos Cheah. Today’s conversation is going to center around RF technology: what it is, common applications and major trends. We are glad to have you joining us for this episode of the program. Tyler (T): Hello, welcome to CONNECTED World, a podcast from TE Connectivity. These connectors are used in television receivers, communications, Wi-Fi devices, avionics, launch vehicles, radar arrays, satellite communications, and industrial or scientific measurement instruments that use RF. Our portfolio of RF coax connectors includes MIL-standard connectors qualified for M39012, M55339, M83517. These connectors are manufactured with crimp, solder, and clamp terminations to enable easy installation. Our RF coaxial cable connectors are engineered and are available in small sizes, with tight tolerance electrical characteristics, and in materials that are rugged but not heavy and manufactured to withstand high use in harsh environments. A coaxial cable connector has an inner conductor that is enveloped by a concentric conducting sleeve, with the conductor and shield separated by an insulating material. An RF connector is commonly used with a coaxial cable due to the shielding that the coaxial cable provides. RF coaxial cable connectors transmit analog signals while minimizing RF (radio frequency) signal losses. These devices are designed to work at the multi-megahertz range of radio frequency. ![]()
