3dB Hybrid Coupler
Aug , 07 2020
The 3dB Hybrid Coupler is also called the same frequency combiner. It can continuously sample the transmission power along a certain direction of the transmission line, and can divide an input signal into two signals of equal amplitude and 90° phase difference. It is mainly used for multi-signal combining to improve the utilization of output signals. It is widely used to combine base station signa...

What is active DAS?
Nov , 07 2020
Active DAS An active DAS converts the analog radio frequency transmissions from the signal source to a digital signal for distribution. A master unit performs this analog-to- digital conversion. The master unit may digitize the signal from a single carrier or multiple carriers. Once converted, the DAS transmits the digital signal over fiber optic or Ethernet cables to remote radio units (RRUs) tha...

Distributed antenna system
Nov , 26 2020
A distributed antenna system, or DAS, is a network of spatially separated antenna nodes connected to a common source via a transport medium that provides wireless service within a geographic area or structure.DAS antenna elevations are generally at or below the clutter level, and node installations are compact. Adistributed antennasystem may be deployed indoors (an iDAS) or outdoors (an ...

What is Hybrid DAS?
Dec , 12 2020
A hybrid DAS A hybrid DAS combines characteristics of passive parts(including RF antenna, directional coupler, power divider,hybrid coupler)and active systems. The RRUs are separate from the antennas, allowing the system to use both fiber optic cable a configuration includes an RRU on each floor that converts from the digital signal to analog RF. The analog RF signal is then connected to multiple ...
