RF Tx/Rx theory is highly complex and years of independent study are needed to achieve mastery of all the details of how electromagnetic variables can affect different application scenarios. RF Tx/Rx refers to the technical theory underpinning transmission and reception of RF (radio frequency) signals. The RF spectrum includes electromagnetic framework frequencies ranging from 30Hz to 300GHz and is commonly divided into several bands organized under low, medium and high frequency.

Countless types of wireless devices use RF signals for transmission and reception including cell phones, radio and television broadcast stations, Wi-Fi and Bluetooth devices, satellite communications systems and two-way radios. RF communication is therefore an essential enabler of society and technologies such as IoT. Of course, it’s unrealistic for device designers and developers to have in-depth RF theoretical knowledge alongside their core expertise, so engineers using Quectel modules can be assured that they don’t need this depth of expertise to successfully design and implement RF circuits into their devices. Quectel experts can guide you on how to use Quectel modules to achieve your objectives and increase efficiency.

This topic was explained in a recent Quectel Masterclass, hosted by Leo Lin, a Quectel FAE, with more than ten years of experience in the wireless industry.  Lin, who specializes in Wi-Fi, Bluetooth, cellular and GNSS RF board-level design, measurement, optimization, debugging and factory production line processes, provides a concise overview of RF Tx/Rx theory fundamentals, helping you gain rapid understanding of how RF works and how to measure key variables, and thereby how to implement RF Tx/Rx into your system development. The Masterclass delivers an overview of RF transceiver architecture, introduces relevant RF filters and shares relevant factors for RF Tx/Rx and how to measure them.
