2.2 ADDITIONAL MODULES FOR 80 W
DTPU DIFFERENTIAL TRANSFORMER
This module contains the differential transformer to obtain the 80 W output
power. This module is located in the additional 3 s.u. shelf.
AMPU HIGH-FREQUENCY AMPLIFIER
This module contains the second 40 W wideband output amplifier and the
alarm circuits for overload or low transmitted-signal level. This module is
located in the additional 3 s.u. shelf.
AFPU LINE FILTER
This module contains the transmit-line filter for the second 40 W amplifier. This
module is located in the additional 3 s.u. shelf.
2.3 ADDITIONAL MODULES FOR AN EXTRA FILTERS FOR 20 AND 40 W
RXPU ADDITIONAL RECEPTION FILTER
This module comprises the receive-channel filter. This module is located in the
additional 3 s.u. shelf.
HIPU ADDITIONAL HF HYBRID
This module contains the high-frequency hybrid. This module is located in the
additional 3 s.u. shelf.
AMPU ADDITIONAL HIGH-FREQUENCY AMPLIFIER
This module contains the wideband output amplifier of 20 W or 40 W and the
alarm circuits for overload or low transmitted-signal level. This module is
located in the additional 3 s.u. shelf.
The output impedance of the HF amplifier must be consistent with the
bandwidth of the line filter, in this way:
AMPU.00 For line filter with bandwidth of 8, 16 or 24 kHz.
AMPU.02 For line filter with bandwidth of 8, 16 or 32 kHz.
