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.
