Ano ang mga tampok ng isang hybrid coupler?

Oras: 2021-10-02 Mga Hit: 15

A hybrid coupler is a passive device which is used in radio and telecommunication systems. In other words, it can also be called a directional coupler, because the input power is equally divided between two output ports. The hybrid coupler provides excellent isolation between the receivers and group delay is extremely small. Hybrid couplers can also be used to split signals from tower top amplifiers to BTS receivers. A 3 dB, 90° hybrid coupler is a four-port device that is used either to equally split an input signal with a resultant 90° phase shift between output ports or to combine two signals. For in-Building distribution systems, hybrids are very useful in carrying multiple carrier inputs because the high degree of isolation between the two output ports and the two input ports without unwanted interaction between carriers .
