CND2047-DAG
RoHS COMPLIANT
9GHz Frequency Divider by 4 Fixed Modulus Prescaler
GaAs Monolithic Microwave IC
Description
The CND2047 is a low power consumption
very high speed divider by 4 GaAs
prescaler manufactured with a 0.7µm self
aligned implanted MESFET process.
The design is full differential input/output
that allows direct drive into 50Ω load.
The CND2047 is available in a low cost
SOIC8 RoHS compliant plastic package.
