In modern electronic devices such as smartphones, Wi-Fi routers, and satellite navigation systems, there is an invisible “messenger” at work—Radio Frequency (RF) communication technology. This wireless transmission method, which uses electromagnetic waves to carry information, is quietly transforming our daily lives. The Fundamentals of RF CommunicationRadio Frequency refers to electromagne……
In today’s connected vehicles, navigation systems do far more than provide turn-by-turn directions. They are tightly integrated with advanced driver-assistance systems (ADAS), vehicle-to-everything (V2X) communication, and smart mobility platforms. At the heart of these capabilities are precise and reliable RF signals—received from satellites and transmitted between modules within the vehicle. Key……
The highly anticipated IME2025 Xi’an 3rd Antenna, Microwave and Satellite Communication Key Technology Conference will be grandly held in Xi ‘an on August 7, 2025! This conference, in an open format of “exhibition + conference”, has built an excellent communication platform for the field of antenna, microwave and satellite communication technology. Attendees will have the opportunity to share……
With the increasing adoption of radio frequency (RF) technology in modern medical equipment—from MRI scanners to therapeutic diathermy machines—ensuring signal integrity and protecting sensitive components have become critical engineering priorities. RF circulators, as non-reciprocal passive devices, play a vital role in managing signal flow and preventing interference in these high-stakes healthc……
In recent years, drone light shows have become a breathtaking spectacle, captivating audiences with synchronized aerial choreography, vibrant lighting effects, and precise formations. Behind these visually stunning performances lies a highly complex communication network that ensures each drone receives accurate and timely control signals. One critical component that helps maintain this reliabilit……
In radar system, the circulator is the core passive device to realise efficient isolation and directional transmission of transceiver signals. Through the non-reciprocal property of ferrite material, it precisely guides the signal flow: when transmitting, it transmits high-power pulses from the transmitter to the antenna port in a directional manner, and when receiving, it guides the weak echoes c……
