3. e this Manual 1 1 Introduction It is recommended that you read this manual prior to installing the Outdoor Band Selective Repeater This manual gives you a complete guide for how to install operate and maintain the product 1 2Structure This manual describes the basic diagram and features and provides overall and detailed functional descriptions of the repeater Also this manual describes how to survey install and operate the equipment The manual is divided into 4 chapters The overall contents of this manual are as follows Chapter 1 How to Use This Manual Chapter 2 Technical Specification Chapter 3 Product Introduction Chapter 4 Operation and Software 1 3 Prior to Installation A thorough study of the site conditions and transmission path requirements should be undertaken prior to installing the repeater system The location of antennas repeater and cable lengths are all important considerations that must be addressed The repeater has been designed for simple easy installation requiring no special tools With just a few site preparation tasks out of the way installation can be accomplished in several hours Notice Redutelco Technology CO LTD has the copyright of this manual Without written permission of Redutelco no part of this document may be reproduced transmitted or translated in any form by any means or for any purpose 2 Technical Specifications Specification Output

6. selective repeaters are commonly used in situations where large numbers of frequency carriers are to be repeated or when base station synthesized frequency hopping is used Band selective repeaters do not separate out specific carriers but amplify and retransmit all signals within a defined frequency band Inter modulation distortion caused by band selective repeaters usually means that lower output power per carrier can be realized compared to channel selective repeaters The adjustable frequency band allocation is a feature enabling less noise and interference caused by signals from operators selective frequency band A band selective repeater with fixed band width has fixed filters for a certain band width A band selective repeater with adjustable band width has filters that can be set to various band widths 3 2System Diagram te BT T J OMT r mmm woman a n mm m m mu s mu m mon mz mm sz mm s mu m mQ sn ms m ms m ms mz ms s s m m s s s s s om a smo The signal from the base station is received via the repeater Donor antenna and is then forwarded through a duplex filter DPX is amplified in a low noise amplifier LNA and enters the band selective amplifier board BSA The first mixer stage on the BSA amplifier board which is controlled by a synthesizer converts the received frequency down to the IF frequency The signal is then filtered by a SAW band pass filter and ampli
