1.9 AWS AND PCS BAND OPTIONS
The Dual-AWS and Dual-PCS DARTs allow you to span non-contiguous bands:
•• the Dual-AWS DART comprises two 6-Timeslot AWS DARTs that span the full 45
MHz of the AWS band
•• the Dual-PCS DART provides two PCS blocks over the entire 70 MHz PCS
spectrum.
In the forward path, the two Remote DARTs are summed together before being sent
to the Linear Power Amplifier (LPA). In the reverse direction, the Low Noise Amplifier
(LNA) is split providing the full PCS or AWS spectrum to each DART. Each DART is
responsible for transporting its own spectrum, as shown in an the following example
for a PCS configuration.
