HIGH EFFICIENCY EQUAL BROADBAND FULL DUPLEX WIRELESS FRONT END CIRCUIT USING SAME RF HYBRID ISOLATION CHARACTERISTICS

摘要

The present invention relates to a high efficiency equal broadband full duplex wireless front end circuit using the same RF hybrid isolation characteristics. More particularly, the present invention relates to a high efficiency equal broadband full duplex wireless front end circuit using the same RF hybrid isolation characteristics including second 3-dB hybrid distributor for transmitting/receiving separation by connecting a transmitter and a receiver to an input terminal and an isolation terminal, respectively. According to the present invention, the high efficiency equal broadband full duplex front end circuit comprises: a first 3-dB hybrid distributor for injecting a portion of a signal from the transmitter into the cancel signal in the receiver; a 0 / 90 combiner for recombining signals branched at the input terminal of the first 3-dB hybrid distributor at the input terminal of the second 3-dB hybrid distributor; and a signal amplitude adjuster (), a phase adjuster (), and a group delay adjuster () for adjusting the amplitude and phase of the signals extracted from the transmitter, and the group delay time.;COPYRIGHT KIPO 2019
