Configuration Numbers ( housing)
Diamond Line 2 amplifier configuration numbers tell which
amplifier module is installed in which housing. For example,
configuration G3A628D37-CVLG94C1 (variable elements
underlined) specifies the following:
•
a Diamond Line 2 amplifier module like the example given
on page 32 (highest forward frequency of 870 MHz, ALSC
pilot frequency of 433.25 MHz, and 10 dB station output
tilt at highest frequency) and
•
a 9-NHD-15 housing (9-NH15 series housing with deep
lid, as required for element management)
. For more on
9-NH housing model numbers, see page 49.
