COFDM-PAL
The amplifier carries
amplification of the generated channels
in the COFDM-PAL transmodulators,
covering a frequency range of 47 - 862
MHz. It disposes of two input signal
connectors for the mixing of channels
coming from two systems. If only one of
the inputs is used, it is advisable to load
the unused input with 75 ohm, ref. 4061.
The amplifier disposes of an output
connector and a Test socket (-30dB)
located at the top of the front panel.
The amplifier is powered with 15V via an
eight-wire flat cable, the same type as
that used for powering the other modu-
les of this system.
