16.10 DC BUC Power On L-Band TX
The MDM9000 offers an optional DC power supply on the L-band TX interface that can be used to
power BUCs. This option combines the L-band transmit signal coming from the modulator with a DC
power supply and an optional 10 MHz reference signal. All these signals can be combined onto the
L-band Tx Interface (N-connector).
The DC power supply (when enabled) provides a 24 V or 48 V DC voltage with a maximum
continuous current of 3.8 A on the L-band TX interface. Both possibilities are available when one of
the following sales option, OU-06 is ordered.
