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...

The difference between duplexer and combiner
Jul , 08 2024
1. Different uses: A. Duplexers are generally used at the output and input ends of equipment to isolate signals of different frequency bands. For example: uplink and downlink signals of mobile communications. B. Combiners are generally used for power synthesis in hardware circuits. For example: to get a 40dbm signal, two power amplifiers with an output power of 20dbm can be used for combining. 2. ...

What is low noise amplifier?
Aug , 24 2024
Low-noise amplifier/LNA is a special kind of electronic amplifier, which is mainly used to amplify the signal received from the antenna in communication system, so as to facilitate the processing of electronic equipment in the later stage. Because the signal from the antenna is generally very weak, low noise amplifiers are generally located very close to the antenna to reduce the loss of the signa...

DAS Explained
Aug , 31 2024
A DAS is a network of antennas, usually in-building, that provides communications over a designated area and is different from a macro tower in that the macro is outdoor and has much higher power covering a wider area. A simple way to understand the difference between a macro tower and a DAS is to consider the difference between a fire hydrant and home faucets. The macro provides massive amounts o...

How much do you know about attenuators?
Sep , 14 2024
Attenuators are important electronic components that are widely used in various electronic devices, especially in communications, instruments and equipment, and test systems. They are mainly used to adjust the size of the signal in the circuit, prevent signal overload, protect instruments and equipment, optimize signal transmission, and improve impedance matching. Attenuators are divided into two ...
