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.

2.2.4 Adjustable Band Edge functional circuit configuration
In case of IDEN using the bandwidth of 800MHz and 900MHz, many of Out of Band Signals is
input via Donor ANT Outdoor. The most worried signal among them is Paging Signal.
