7.1 General
The CBA series has an RF In, RF Out and a built in dual directional coupler with N-
Type forward and reflected connections. These are available in two configurations,
either all on the front or all on the rear of the amplifier. The CBA series are equipped
with either a N-Type or a 7/16
th
RF output connecter (model dependent, see applicable
datasheet) but the same standard shall still apply; all RF connections are either on the
rear or on the front of the amplifier. The interlock, remote connections, AC connector,
and interconnecting cables are always located on the rear panel.

CAUTION!
The maximum input level detailed in the specification sheet and on the
amplifier front panel must not be exceeded. Do not expose the centre pin of
the RF-input connector to static discharge. The signal source must be at DC
zero.
Refer to the specification sheet for details of RF input levels. The nominal input
impedance is 50 ohms.

Hints and tips:
Don’
t forget that modulated or complex signals may have a peak
power that may not be indicated on the signal source. Always ensure that the peak
level of the input signal is within the limits specified in the applicable datasheet.
