Page 12: Rd-8132 Repeater Introduction
INSTALLATION GUIDE FOR RD-8132 1 RD-8132 REPEATER INTRODUCTION The RD-8132 split band-selective repeater is designed for GSM850 band. A band-specific linear amplifier and filtering effectively amplifies the desired BTS carriers and provides superior out-of-band rejection. The unit can incorporate two 2~15 or 1~6MHz bandwidth adjustable segments. Remote configuration and surveillance is possible through Comba’s remote control and monitoring system via PC or wireless modem... -
Page 13: Equipment Description
External Power Figure 2: RD-8132 functional block diagram In the downlink, the BTS signals are received by donor antenna of the repeater. After the duplexer, the signals are sent to the LNA module for pre-amplification, followed by band selection by the Frequency Select (FS) modules. -
Page 14: Equipment Layout
Lock Figure 3: Layout of the RD-8132 Typical RD-8132 units consist of the following components: Low Noise Amplifier (LNA) One Low Noise Amplifier (LNA) is installed at the front end of the UL and DL branches. The use of LNAs gives better sensibility to the repeater. - Page 15 INSTALLATION GUIDE FOR RD-8132 Duplexer (DPX) The DPX located towards the DT and MT connections permits the uplink and downlink signals to share a common antenna. Li-ion Battery The Li-ion battery pack is enclosed within a plastic cover and provides back-up supply to the MCU for up to three hours in the event of mains failure.
