The multi-carrier operating environment is further complicated by the number of
carriers that are transmitted through the amplifier. The largest degradation in distortion
occurs when going from two carriers to three carriers.
Figure 4-4
shows the intermod
performance vs. number of carriers for 2, 3, 6, and 10 carriers. As the figure shows
after approximately 10 carriers the intermod performance flattens and approaches that
of a noise power ratio (white noise) performance.
4.3 Mute/Un-mute Switch Time
The HPA can be muted either via the front panel key or via a remote signal through the
M&C software.
Muting the amplifier via the front panel requires 100 msec maximum (50 msec
typical).
Muting the amplifier via remote M&C requires 70 msec maximum (30 msec typical).
