In the twilight, the ancient city walls of Xi'an glow with a faint bluish-gray halo. The historical scent seeping through the cracks in the bricks intertwines silently with the aroma of coffee from the street corners. The city is like a well-worn, ope

The world of radio frequency (RF) involves signals across multiple frequency ranges, which we discuss within the broader context of the "electromagnetic spectrum." While light and very low-frequency radio waves have specific uses within the electromagnetic spectrum, light communication is distinct from mid-frequency el……

Like passive components, active components used in RF circuits share many characteristics with those typically found in low-frequency analog systems. Different semiconductor technologies are often employed to ensure that RF components maintain adequate pe

There are several different methods for demodulating frequency-modulated signals; on this page, we will discuss two of them. 1. Generate a signal To explore FM demodulation using LTspice, perform frequency modulation so that

1. CPWG structure Traditional CPW CPW The traditional CPW features a G-S-G configur……

An RF switch is a component that allows mobile phones to switch between different RF signal paths, acting like a bridge for signals to continuously connect or switch between pathways. RF switches have a wide range of applications and are indispensable com

In our conventional understanding, passive RF devices are considered linear components. Parameters such as the coupling coefficient of couplers, losses and attenuation of filters, and gain of antennas are typically managed by adding or subtracting their r

1. Components and operating principles of a VNA The vector network analyzer (VNA) mainly consists of an excitation source, a power distribution a……
