<Pic.3> iDEN 15dBm PORT design
2.2.2 Downlink Path
There are four (4) parts of downlink Block in iDEN In-building RF Repeater.
- Filter part for Multiplex four (4) bands as each 800MHz and 900MHz TX/RX in Front End of
Donor/Server
- LNA part of Donor/Service path to process signals of 800MHz and 900MHz bands.
- 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.
