Datum 6502 Data Sheet

DATUM 6502
RF DISTRIBUTION

The DATUM 6502 Distribution Module packages the well tried

and tested DATUM high performance distribution technology in a

convenient 1U high unit to distribute high quality RF sine wave

signals. The unit houses a set of very low phase noise RF

amplifiers while maintaining high isolation (>100 dB) between

output channels. Up to ten units can be

daisy chained

to give up

to 100 outputs, or each output of one unit can be used as a

source for other DATUM 6502 units, to give almost infinite

expansion capability with virtually no signal degradation.

KEY ADVANTAGES

• Low Phase Noise

• High Channel Isolation

• Ten Channel Output Distribution

•

Daisy Chain For More Than 100 Outputs
