AA116-72

DATA SHEET AA116-72, AA116-72LF: GaAs IC 1-Bit Digital Attenuator 15 dB LSB DC–2 GHz Features 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 ● Pin Out J1 RF GND J2 CBL V2 1 2 15 5 CBP 4 CBL V1 3 Description 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. 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. NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.

CAUTION: Although this device is designed to be as robust as possible, ESD (Electrostatic Discharge) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions must be employed at all times. 0.037 (0.95 mm) Ref. 0.012 (0.30 mm) Typ. 0.024 (0.61 mm) 0.004 (0.10 mm) 0.122 (3.10 mm) 0.106 (2.70 mm) 0.0104 (0.26 mm) 0.0035 (0.09 mm) Min.
