iDEN 30dBm

- 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.
