CDMA2000 technology deployment in the 450MHz band offers significantly larger cell size than any other 3G cellular network. However, there are always ‘coverage hole’ due to fading and shadowing. Thus, repeaters being the quick and economical solution; have been widely used to fill the gap in coverage. This paper presents the Power Amplifier (PA) module that has been designed and developed for CDMA450 repeater. The repeater system design is introduced beforehand to put the PA module into perspective. Then, the PA design requirement and methodology are presented. Based on the lab testing, the proposed PA module offers 70dB gain and output power up to 43dBm such that it can be used within a 10Watt repeater system. [ABSTRACT FROM PUBLISHER]

This paper intends to share the deployment experience of CDMA450 repeater for a distinctive indoor structure. Firstly, the CDMA450 technology is introduced, in particular the coverage advantage. Even so, CDMA450 operators have to deal with shadowed and dead spots in network planning. Hence, the importance of repeaters in solving the issues regarding the coverage hole with minimum cost is presented. This paper also reviews the repeater design for CDMA450 application which later, a real deployment case is presented to show the potential of the prototype. From the field test results, the in-house developed repeater has shown reliable performance for indoor coverage enhancement of a convention center by improving the Ec/I0. [ABSTRACT FROM PUBLISHER]
