General Description of RF Broad Band Repeater(Outdoor) 1.1. System Overview RF Broad Band Repeater(Outdoor) is designed for increasing both coverage and capacity in cellular systems. It receive CDMA signal from BTS and emits RF signal where the coverage is required. RF Broad Band Repeater(Outdoor) receives CDMA signal from BTS via directional antenna and filters out the signal through BPF(Band Pass Filter) then amplifies CDMA signal to proper level through LNA(Low Noise Amplifier). The signal passes through middle amplifier and is amplified to proper level through HPA(High Power Amplifier). Then the repeater emits RF signal to blank area via antenna. Also RF Broad Band Repeater(Outdoor) receives the RF signal from mobile station. After filtering out the signal through BPF(Band Pass Filter), the repeater amplifies the signal using LNA(Low Noise Amplifier). The signal passes though middle amplifier and is amplified to proper level through HPA(High Power Amplifier) then emits CDMA signal to BTS via antenna. The repeater is projected to make BTS coverage wide cost-effectively. Optional features of the products include modified frequency ranges and bandwidths, non- standard connectors and design flexibilities to satisfy the most stringent requirements. Figure 1.
