The difference among power splitter, coupler and combiner
Power splitter,coupler and combiner are important components for RF system, so we would like to share its difference among them on their definition and function. 1.Power divider: It equally divides the signal power of one port to the output port, which is also named as power splitters and, when u...Read more -
The impact of RF passive device design and manufacturing on applications
According to design and manufacturing principles and production processes, passive devices used in the current network can be divided into cavity and microstrip types. Cavity devices mainly include cavity components, cavity filters, cavity couplers and hybrid, and microstrip devices mainly includ...Read more -
How to Design Dielectric Filter?
A Dielectric Filter is an optical fiber that selectively transmits one wavelength and reflects others based on Interference inside the structure. Also called interference filter. Microwave dielectric effects ceramics improve the size of devices and the packaging density ...Read more -
What Will 6G Bring to Humans?
4G changes life, 5G changes society, so how will 6G change humans, and what will it bring to us? Zhang Ping, an academician of the Chinese Academy of Engineering, a member of the Advisory Committee of the IMT-2030(6G) Promotion Group, and a professor at Beijing Universi...Read more -
Effects of RF passive component applications on wireless communications
In recent years, for the purpose of saving costs and reducing duplication of construction, many indoor distribution systems have adopted the model of a multi-combined system that shares a room with other sub-systems. This means that multi-system and multi-band signals ar...Read more -
What parameter should be mainly considered when to pick RF filter ?
When designing RF solution, RF filters play prominent roles in the system. If picking RF filter, the following parameters should be considered. 1. Center frequency: f0 is short for the center frequency of the passband of the RF filter, which is generally taken as f0 = (f...Read more -
How to debug the passband of a tunable filter with typical bandwidth？
In order to statisfy the applications flexibly, Jingxin develops the tunable filters for the client to debug by themselves, and offers the guideline to rightly tune it as the following example of VHF filter. 1. Re-tuning procedure for tunable filter JX-SF1-152174-215N Th...Read more -
How to distribute RF passive components in antenna system?
Radio frequency passive components are mainly used in the construction of wireless communication system base stations, and indoor distribution systems. Especially in the wireless signal in the building, there are many kinds of applications in the indoor distribution cove...Read more -
What is RF / Microwave Filter?
Radio frequency (RF) & microwave filters are defined as a kind of electronic filter, which are designed to operate on signals in the megahertz to gigahertz frequency ranges (medium frequency to extremely high frequency). This frequency range of the filter is the rang...Read more -
How to design a miniaturized system to integrate passive and active components on a “filter carrier”?
As technology advances, the telecom industry is keening on smaller, lighter communication systems, today we’d like to introduce how to take a cavity filter as a module carrier to design a miniaturized system to integrate passive and active components, and what’s its adva...Read more -
How do active components differ from passive ones?
In RF systems, active and passive devices are often used, so what are active devices, what are passive devices, and what are the differences between them? (i) Definition: An active component must be operated with a power supply inside it. A passive component is operating...Read more -
