Description
Summary: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.
