<Pic.4> iDEN In-building RF Repeater Downlink Block Diagram
2.2.3 Uplink Path
Uplink Block of iDEN In-building RF Repeater is separated as four (4) parts.
- Filter part for Multiplex four (4) bands as each 800MHz and 900MHz TX/RX in Front End of
Donor/Server
- LNA Part of two(2) paths for processing 800MHz and 900MHz signals
- 800MHz IF Converter part and 900MHz IF Converter part of 5MHz band having Switching filter parts
for selecting each 18MHz and 7MHz.
- Power Amplifier part for power amplifier and Level Monitoring/VSWR monitoring to adjust desirable
output power of Repeater
800MHz IF Converter part is designed to select single path, and it can be minimizing signal interference
between paths, and power consumption according to controls of electric power in each SAW Filter part.
