General Dynamics SATCOM Technologies (formerly VertexRSI) BU-Series Block Upconverters are specifically designed to translate a block of
L-Band input frequencies to either C-Band or Ku-Band. These block upconverters have the quality, stability and performance
required for demanding transmitting applications in INTELSAT, EUTELSAT, and other satellite communications systems. When used
with VertexRSI's line of Solid-Sate Power Amplifiers (SSPAs), the BUC-Series converters will shift the SSPA input frequency
to L-Band for use with coaxial or fiber optic IFLs.
C-Band or Ku-Band Output
Locks to External 10 MHz Reference
Low Phase Noise
Type N Connectors
The BUC-Series Converters may be powered by one of two methods. Either supply +10.5 to +18 Vdc between the center conductor and
ground of the L-Band input cable (cable powered) or apply +10.5 to +18 Vdc to the DC power RFI and the ground lug.
The 10 MHz reference is applied to the L-Band input cable along with the L-Band signal, and should be applied using a diplexer.
The alarm RFIs provide a Form-C contact which indicates a fault if phase lock is lost.
The alarm circuit is rated at 100 V at 50 mA.
