DATA SHEET AA116-72, AA116-72LF: GaAs IC 1-Bit Digital Attenuator 15 dB LSB DC–2 GHz Features Pin Out 3 V control ● Low loss ● Low-cost SOT-5 plastic package ● Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 °C per JEDEC J-STD-020 ● 5 4 V1 15 CBP CBL 3 NEW J2 V2 CBL 2 The AA116-72 is a 1-bit GaAs IC FET digital attenuator in a lowcost package. This attenuator has an LSB of 15 dB. The AA116-72 is particularly suited where high attenuation accuracy, low insertion loss, and low intermodulation products are required. Typical applications include cellular radio, wireless data, and wireless local loop gain level control circuits. RF GND 1 Description J1 DC blocking capacitors (CBL), bypass capacitor (CBP), and biasing resistor must be supplied externally for positive voltage operation. CBL = 33, CBP = 39 pF for operation @ 900 MHz. Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.
