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...

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...

What's low PIM?what's the Importance of Low-PIM?
Aug , 06 2022
Low PIM means stronger signal,which means higher revenue for happy customers and operators. From a hardware perspective, this means that every connection must be designed to minimize PIM and tested to ensure proper installation. In order to understand the importance of low PIM antennas, Low PIM Combiner and Low PIM Splitter/Coupler in 5G networks, it is critical to understand what PIM refers to. P...

RF Dummy Load
Aug , 20 2022
What is dummy load? A dummy load is a device used to simulate an electrical load, usually for testing purposes. In radio a dummy antenna is connected to the output of a radio transmitter and electrically simulates an antenna, to allow the transmitter to be adjusted and tested without radiating radio waves. What does a dummy load consist of? So a dummy load usually consists of a composite resistor,...

radio frequency combiner
Sep , 12 2022
The circuit breaker is generally used at the transmitter. It combines two or more radio signals sent from different transmitters into an RF device transmitted by the antenna. At the same time, the interaction between signals at different ports is avoided. A circuit breaker typically has two or more input ports and only one output port.Port isolation is an important indicator that describes the cap...
