Description
The AA116-72LF is a one-bit GaAs FET digital attenuator in a low-
cost SOT-5 package. The device has a Least Significant Bit (LSB)
of 15 dB and is particularly suited where high attenuation
accuracy, low insertion loss, and low intermodulation products
are required.
A functional block diagram is shown in Figure 1. The pin
configuration and package are shown in Figure 2. Signal pin
assignments and functional pin descriptions are provided in
Table 1.

Evaluation Board Description
The AA116-72LF Evaluation Board is used to test the performance
of the AA116-72LF digital attenuator. An assembly drawing for
the Evaluation Board is shown in Figure 7 and an Evaluation
Board schematic diagram is shown in Figure 8.
Package Dimensions
The PCB layout footprint for the AA116-72LF is shown in Figure 9.
Typical case markings are noted in Figure 10. Package
dimensions for the 5-pin SOT-5 are shown in Figure 11, and tape
and reel dimensions are provided in Figure 12.
Package and Handling Information
Instructions on the shipping container label regarding exposure to
moisture after the container seal is broken must be followed.
Otherwise, problems related to moisture absorption may occur
when the part is subjected to high temperature during solder
assembly.
THE AA116-72LF is rated to Moisture Sensitivity Level 1 (MSL1) at
260 C. It can be used for lead or lead-free soldering. For
additional information, refer to the Skyworks Application Note,
Solder Reflow Information, document number 200164.
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment.
Production quantities of this product are shipped in a standard
tape and reel format.
