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.
