CND2047
10GHz 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 chip form
and in 2 packages form:
* low cost SOIC8 plastic package
* 8 lead Flat Pack ceramic surface mount
package
2047
