UMS CND2047

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.
2047
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
FTP8 ceramic package

Recommended bonding
Bonding pads of the product are covered
with aluminium metallic layer.
Wedge or ball bonding can be used.
Aluminium wire has be used if the
assembly process is up to 250°C.
Otherwise the use of gold wire is possible.
The ground bounding length should be as
short as possible to optimize the use of the
product.
The bonder should be properly grounded.
