Description
M/A-COM's AT90-1107 is a GaAs FET 6-bit digital
attenuator with integral TTL driver. Step size is 0.5
dB providing a 31.5 dB total attenuation range. This
device is in an PQFN plastic surface mount
package. The AT90-1107 is ideally suited for use
where accuracy, fast speed, very low power
consumption and low costs are required.
supply designs without switching noise, use AT90-
0107.
