4.0 Block Up Converter Overview
The Compact Outdoor SSPA is available with various L-Band up converter options. The
primary up converter option is the Zero dBm Block Up Converter, ZBUC
TM . The ZBUC
converter is offered in four C-Band configurations, two Ku-Band options, and one X-Band
model. See Table 5-1 for specifications for the respective models. The ZBUC converter offers
ultra low phase noise for applications where phase noise is an overriding factor.
The type of BUC housed within your Compact Outdoor SSPA is indicated by its model
number, as shown in Figure 4-1. The example in Figure 5-1 shows a 140W C-Band
Compact Outdoor SSPA with Internal Reference ZBUC. For a full description of this
configuration matrix, refer to the Compact Outdoor SSPA specification sheet (205485).
The block up converters are high performance frequency translation devices which
provide excellent phase noise and spurious performance. The ZBUC converter also supports
FSK communications for remote M&C capability. The FSK is a 650 KHz signal that is multi-
plexed onto the L-Band input of the unit.
The ZBUC converter utilizes Teledyne Paradise Datacom’s proprietary “Smart Reference
Technology”. Smart Reference Technology allows the system user to change reference
frequency and power level or choose internal or external reference without requiring any
system configuration. An internal BUC adds about 1.7 pounds to the overall weight of the
Compact Outdoor unit.
The schematic of Figure 4-2 shows the electrical position of the block up converter. It is
powered from a +15 VDC supply available on the Fan Boost Converter board assembly. The
Block Up Converter is simply cascaded with the SSPA at the input of the amplifier.
