IS-95C coupler for Optical repeater for Cell extension of IS-95A/B & IS-95C service
CDMA 통신용 IS-95A/B, IS-95C 서비스의 Cell 확대를 위한 광중계기 연결보조장치
Abstract
A system, IS-95C coupler that combines the signals of IS-95A/B and IS-95C BTS and compensates the differences between the signals of two systems and connected to optical repeater If no IS-95C coupler exist, Optical repeater can't service of signal balanced. A system carries on combination, amplification, level modulation function of the TX signals(IS-95A/B & IS-95C) and division and level modulation function of the RX signals. Isolation satisfied above 100dB.
