4.0 Block Up Converter Overview
The Mini Compact Outdoor SSPA is available with various converter options, utilizing
Paradise Datacom’s integrated converter. The primary up converter option is offered in two
C-Band configurations, two Ku-Band options, and one X-Band model. The BUC offers ultra
low phase noise for applications where phase noise is an overriding factor. For specifications,
see
Table 4-1
.
The type of BUC housed within your Mini Compact Outdoor SSPA is indicated by its model
number, as shown in
Figure 4-1
. The example listed shows a 100W C-Band Mini Compact
Outdoor SSPA with Internal Reference BUC. For a full description of this configurator, refer to
the Mini Compact Outdoor SSPA specification sheet (208142).
The block up converters are high performance frequency translation devices which
provide excellent phase noise and spurious performance. The converter also supports FSK
communications for remote M&C capability. The FSK is a 650 KHz signal that is multiplexed
onto the L-Band input of the unit. See
Section 4.4
for more detail.
The converter utilizes 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 reconfiguration.
The schematic of
Figure 4-2
shows the electrical position of the block up converter.
It is important to remember the requirement of a reference oscillator when operating an SSPA
with BUC (SSPB). If the reference is not present, the M&C will report a BUC alarm and the
SSPA module will mute. This ensures that no spurious or ‘off frequency’ transmission could
originate from the amplifier.
