RF chips (Radio Frequency Integrated Circuits, RFICs) are specialized integrated circuits used to process radio frequency signals. These chips are widely utilized in wireless communications, radar, satellite communications, and RF measurements. As the core of modern communication systems, RF chips are responsible for a series of key tasks including signal reception, transmission, amplification, frequency conversion, and modulation-demodulation.
