Characteristics
GST’s In-buildingrepeater is basically a combination of 800MHz 25dBm repeaters. Functional
modules are classified as below:
- Cavity Filters to combine the Duplex input/output signals for: 800MHz.
- LNA (Low Noise Amplifier)
Gain Block to transmit output signal to PAM (Power Amplifier Module)
- Cavity Filter
- Converter Modules
- PAM Module to amplify output power linearly in accordance with optimal repeater output
power.
- Power Supply Unit
- Controller to monitor each module in repeater.
Abbreviation
