Model Numbers (module only)
Diamond Line 2 amplifier models vary in three ways: highest
forward frequency, automatic level and slope control (ALSC)
pilot frequency, and station output tilt. For example, model
6-G3A298/37–42/54–433–100 (variable elements
underlined) specifies the following:
•
a highest forward frequency of 870 MHz,
•
a 433.25 MHz ALSC pilot frequency, and
•
10 dB station output tilt over the forward bandwidth.
