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 ...

Diplexer and duplexer
Apr , 20 2024
Regarding RF passive componenst, we always use duplexer and diplexer, which maybe confused. what is the difference between duplexer and diplexer? RF Diplexers are 3-port RF devices, which allow the use of two signal paths on the same transmission line (such as an antenna). This is achieved through filters that separate the frequencies of interest, allowing signals at two different freque...

What is a repeater and what does it do?
May , 08 2024
Repeater (RP repeater) is a connecting device working on the physical layer. It is suitable for interconnecting two identical networks, and its main function is to extend the network transmission distance by retransmitting or forwarding data signals. Repeaters are network devices that regenerate and restore signals: physical layer devices of the OSI model. In the field of communications, a repeate...

Resolving Directional Antennas
Jul , 06 2024
In reality, all types of RF antennas have some degree of directionality. However, there are certain antenna designs and types that are particularly directional compared to other antenna types. A Directional Antenna is useful in applications where it is desirable to receive a signal from a specific direction of origin or otherwise transmit a signal in a specific direction. The directivity of an ant...

Bandpass cavity filter
Nov , 09 2024
A band-pass filter is a device that allows a certain range of frequencies to pass while blocking others, such as RLC oscillator which is an analog band-pass filter. A bandpass filter refers to a filter that can pass a certain range of frequencies without attenuation while reducing other of frequencies to a very low level. This concept is opposite to that of a band-stop filter. 2. An ideal fi...
