5.0 Block Up Converter Overview
Teledyne Paradise Datacom SSPAs are available with various L-Band up converter options.
The primary up converter option is the Zero dBm Block Up Converter, zBUC
TM
. The zBUC
block up converter is offered in four C-Band configurations, two Ku-Band options, and one
X-Band model. See
Table 5-1 for specifications on the respective models. The zBUC
TM
offers
ultra low phase noise for applications where phase noise is an overriding factor.
The type of BUC housed within your SSPA is indicated by its model number, as shown in
Figure 5-1 . The example in Figure 5-1 shows a 800W C-Band 7RU Rack Mount SSPA with
Internal Reference zBUC converter. For a full description of this configuration matrix, refer to
the 7RU Rack Mount SSPA specification sheet (208114).
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 multiplexed
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 zBUC converter adds about 1.5 pounds to the overall weight
of the SSPA.
