Introduction
The AC1500 is a single active output amplifier with 43 dB operational gain.
Integrated interstage gain and slope controls optimise flatness performance and
together with a transponder or a pilot detection module add ALSC functionality.
Temperature compensating MLSC unit minimises the needed amount of ALSC
units. With internal splitting there are 3 separate outputs available
The amplifier stages are based on high performance GaN hybrids, which makes
the usable output level range especially wide. The platform and accessories of
AC1500 are fully functional up to 1.2 GHz.
Elements like ingress switches and return amplifier are built on the
motherboard. For upgrading return path to 85 MHz or 204 MHz there is no need
to change return amplifier, but only diplex filters and a passive slope and
response correction unit. Continuous rotary switch upstream controls are built
on the motherboard
