8/26
- If Converter part having several bands of SAW Filter paths to adjust Band Edge of high
frequency as 200KHz and 400KHz each. In case of 800MHz band, extra Switching Filters
equipped to individually select 18MHz and 7MHz
- Power Amplifier part for power amplifier and Level Monitoring/VSWR monitoring to
adjust desirable output power of Repeater
Downlink frequency contains lots of signals such as Paging signal, DCS etc through Donor ANT.
So Out band signals should be minimized by SAW filters having excellent Roll off characteristics
for the best optimized operation.
