Television Antennas
May , 30 2022
Television antennas are devices that allow you to catch waves at television frequencies and watch television programs. They need to be strong enough to catch up and amplify any kind of television signals, in order for you to get a good reception and be able to connect and watch a number of channels at the same time. So, a television antenna is used to amplify television signal, and it can also hav...

What is the difference between band-reject filter and bandpass filter?
Jul , 01 2022
A bandpass filter is an electronic device or circuit that allows signals between two specific frequencies to pass, but that discriminates against signals at other frequencies.In signal processing, a band-reject filter (also called a band-stop or notch filter) is a filter that passes most frequencies unaltered, but attenuates those in a specific range to very low levels. The main difference between...

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...

Power dividers and directional couplers
Aug , 11 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. An essential feature of di...

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...

What are 5G frequency bands
Oct , 21 2022
What are 5G frequency bands Like any wireless transmission system, 5G – the fifth generation mobile communication network also require to use frequency spectrum to transmit data. In order to support higher bandwidth, 5G require high frequency range of sub 6 GHz and millimeter waves. What are the radio frequency bands used in 5G communication system? Why 5G requires high frequency spectrum? Convent...

DAS & Small Cells: What’s The Difference?
Oct , 28 2022
The radio heads of a distributed antenna system are essentially “dummy” radio heads: these access points don’t provide any signal processing like a small cell antenna system would. Instead, DAS radio heads relay the signal to a cellular base station located at a central hub. Once the signal is relayed to the hub, it’s processed at that central location. Base stations installed at a central hub are...
