Description
M/A-COM’s MAAD-009260-000100 is a GaAs FET
2-bit digital attenuator with two 16 dB steps and 32
dB total attenuation. The design has been optimized
to minimize phase variation over the attenuation
range. This attenuator and integral TTL driver is in a
hermetically sealed ceramic 16-lead surface mount
package.
The MAAD-009260-000100 is ideally
suited for use where accuracy, fast switching, very
low power consumption and low intermodulation
products are required. Typical applications include
dynamic range setting in precision receiver circuits
and other gain/leveling control circuits. Environ-
mental screening is available. Contact the factory
for information.

8. C1 is specified as the control for the 16 dB bit. We show
data for the performance with the C2 control - note that the
power handling is reduced if C2 is used for the 16 dB bit.
The electrical performance of the 16 dB bit controlled by
C2 is not specified.
