Functional Schematic
Description
M/A-COM's AT90-1106 is a GaAs FET 6-bit digital
attenuator with integral TTL driver. Step size is 1 dB
providing a 50 dB total attenuation range. This
device is in a PQFN plastic surface mount package.
AT90-1106 is ideally suited for use where accuracy,
fast speed, very low power consumption and low
costs are required. For dual supply designs without
switching noise, use AT90-0106.

1. The exposed pad centered on the package bottom must be
connected to RF and DC ground. (For PQFN Packages)
2. Pins 10 & 29 must be isolated
3. -Vee is produced internally and requires a .1µF cap to GND.
Generated noise is typical of switching DC-DC Converters.
