Main functions of coupler
Mar , 29 2023
Coupler I believe many people have heard of it. What is it? In fact, it is a device that transfers power between systems. In microwave systems, it is often necessary to divide one channel of microwave power into several channels in proportion, which is the issue of power allocation. The components that achieve this function are called power distribution components or couplers, which mainly include...

Are UHF and VHF antennas the same?
Jul , 12 2023
VHF antennas and UHF antennas use very high frequency (VHF) and ultra-high frequency (UHF) signals for two-way radio, public safety, and commercial communications. VHF is the range of radio frequency (RF) signals from 30 to 300 MHz. UHF is the range between 300 MHz and 3 GHz.

Vibration Test
Sep , 01 2023
Vibration test is often used to simulate actual vibration in a typical or worst-case scenario. Typically, the severity of the test is significantly higher than typical real-world vibration levels. This is done in order to conduct tests that simulate the life of rf passive components(rf directional coupler,2way power splitter,etc)over hours, days, or weeks. There are also milder tests, such as envi...

What is the difference between coupler and hybrid coupler?
Sep , 08 2023
Do you have a question about What the difference between coupler and hybrid coupler is ?Actually,My answer is Yes. An essential feature of directional couplers is that they only couple power flowing in one direction. Power entering the output port is coupled to the isolated port but not to the coupled port. A directional coupler designed to split power equally between two ports is called a hy...

What is directional antenna?
Oct , 20 2023
Directional antenna is relative to omni-directional antenna, which radiates in a certain angle range on the horizontal direction diagram, that is, it is usually directional. Like omni directional antenna, the smaller the lobe width, the greater the gain. Directional antennas are generally used in communication systems with long communication distance, small coverage, high target density and high f...

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 ...
