Definition of VSWR
Apr , 26 2024
Standing Wave Ratio is called Voltage Standing Wave Ratio, also known as VSWR and SWR, which is the abbreviation of English Voltage Standing Wave Ratio. In the incident wave and the reflected wave phase of the same place, the voltage amplitude is added to the maximum voltage amplitude Vmax, the formation of the wave belly; in the incident wave and the reflected wave phase of the opposite place the...

Diplexer and duplexer
Apr , 20 2024
Regarding RF passive componenst, we always use duplexer and diplexer, which maybe confused. what is the difference between duplexer and diplexer? RF Diplexers are 3-port RF devices, which allow the use of two signal paths on the same transmission line (such as an antenna). This is achieved through filters that separate the frequencies of interest, allowing signals at two different freque...

What is a coaxial isolator and its function
Mar , 16 2024
A coaxial isolator is a passive electronic device that is commonly used in RF (Radio Frequency) and microwave systems. Its primary function is to provide isolation, which means it prevents undesired signals or reflections from traveling back along the transmission line. The isolator is usually inserted between two components or systems to ensure signal integrity and protect sensitive devices from ...

Directional Coupler
Feb , 05 2024
A directional coupler is a general-purpose microwave/millimeter-wave component, an RF passive device commonly used in RF circuit design as a power distribution element with directionality. It is a four-port element that is usually formed by combining two sections of transmission line called the straight-through line (primary line) and the coupled line (secondary line). Straight through the l...
