Description

The AA109-310 is a GaAs FET IC 5-bit digital attenuator with a serial-to-parallel driver packaged in a 32-leadless exposed pad plastic package. It is particularly suited where high attenuation accuracy, low insertion loss, and low intermodulation products are required. Typical applications include base station, wireless and wireless local loop gain control circuits.

Features

● Positive voltage operation (5 V)

● QFN 5 x 5 mm leadless package

● Integrated silicon serial-to-parallel driver

● Attenuation 1 dB steps to 31 dB

● Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 °C per JEDEC J-STD-020

AA109-310属于RF/IF，射频/中频和 RFID > 衰减器。美国思佳讯公司制造生产的AA109-310衰减器衰减器旨在降低信号功率，同时尽量减少其对波形的影响。衰减值的范围为 0 dB 至 69 dB，频率范围为 0 至 86 GHz。
