The operating frequency range (bandwidth) of the antenna
Mar , 12 2022
Whether it is a transmitting antenna or a receiving antenna, they always work within a certain frequency range (frequency bandwidth). There are two different definitions for the frequency bandwidth of an antenna—— 1. The working frequency bandwidth of the antenna under the condition that the SWR ≤ 1.5; 2.The b...

Automatic Soldering Machine
Apr , 16 2022
The company bought a new kind of equipment, an antomatic soldering machine. This device can speed up the soldering workflow on the production line. Automatic soldering eases the work pressure on a designer up to a considerable level and the end product is also much more better as compared to manual soldering. Among the various tasks that are needed to be performed for building up a circuit, it is ...

What is a power splitter
Apr , 21 2022
Power dividers (also power splitters and, when used in reverse, power combiners) and directional couplers are passive devices used mostly in the field of radio technology. They couple a defined amount of the electromagnetic power in a transmission line to a port enabling the signal to be used in another circuit.There are wilkinson power splitter and cavity power splitter or reactive Power Splitter...

The difference among power divider, directional coupler and combiner
Jul , 11 2022
RF Power divider: a power divider that equally distributes signal power from one port to the output port; RF Combiner: Power synthesis, which adds two or more signals to a port; RF Directional coupler : The proportional coupling of a signal to a coupling port. The power splitter is reversed and is a combiner.A coupler can be considered a kind of power divider, but not equally divided. Power divide...
