AA113-310LF

Attenuators Overview

The AA113-310LF is a programmable RF attenuator manufactured by Skyworks Solutions Inc. It operates within a frequency range of 0 Hz to 1 GHz and provides an attenuation span from 0.5 dB to 31.5 dB. The device supports a maximum power handling capacity of 2W and maintains a characteristic impedance of 50 Ohms. It is housed in a 32-VFQFN package with an exposed pad, designed for surface-mount technology (SMD/SMT) applications.

Attenuators Procurement Notes

Verify the specific datasheet version and RoHS compliance status prior to procurement. Confirm that the 32-VFQFN footprint matches the target PCB layout requirements. Ensure thermal dissipation capabilities are adequate for the intended 2W power handling environment during system integration.

Attenuators Selection Notes

Select this component when a wide dynamic range of attenuation is required across a broad frequency spectrum up to 1 GHz. Consider the 50 Ohm impedance match for standard RF interfaces. Evaluate the 32-VFQFN package size constraints against available board space and thermal management needs for high-power RF applications.
