CPI SAT BD12SJ-I2 BD Series Ku-Band Block Downconverter (11.70 - 12.75 GHz)

BD12SJ-I2 Ku-Band Block Downconverter

The CPI SAT (formerly GD Satcom Technologies & Prodelin) BD12SJ-I2 BD-Series Block Downconverters are designed to translate a block of L-Band IF input frequencies to Ku-Band (11.70 - 12.75 GHz). These block downconverters have the quality, stability and performance required for demanding transmitting applications in INTELSAT, EUTELSAT, and other satellite communications systems. When used with Solid-State Power Amplifiers (SSPAs) the BU-Series converters will shift the SSPA input frequency to L-Band for use with coaxial or fiberoptic IFLs.

Application Notes BD-Series converters may be powered by one of two methods: Either supply +Vdc between the center conductor and ground of the L-Band input cable (cable powered) or apply +Vdc to the DC power RFI and the ground lug. The alarm RFIs provide a Form ‘C’ contact set which indicates a fault if phase lock is lost. The alarm circuit is rated at 100 V at 50 mA.
