| DATA SHEET AA226-87, AA226-87LF: GaAs IC 4-Bit Digital Attenuator, 1 dB LSB LF-2.5 GHz Features Pin Out CBL 16 Attenuation 1 dB steps to 15 dB with high accuracy Single positive control (3 to 5 V) for each bit Low DC power consumption Small low-cost TSSOP-16 plastic package Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 C per JEDEC J-STD-020 J1 GND GND V1 V2 V3 V4 GND 1 8 dB 2 3 15 14 GND GND GND GND GND GND VS 10 k 4 dB 4 5 13 12 2 dB 6 7 11 10 Description The AA226-87 is a 4-bit, single positive control GaAs IC FET digital attenuator. It requires DC blocking capacitors, positive supply voltage (VS) and four individual positive bit control voltages (V1-V4). The AA226-87 is particularly suited where high attenuation accuracy, low insertion loss and low intermodulation products are required. Typical applications include base station, wireless data and wireless local loop gain control circuits. 1 dB GND 9 DC blocking capacitors (CBL) and biasing resistor must be supplied externally for positive voltage operation. CBL = 47 pF for operation >500 MHz. 8 CBL J2 NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.
