The attenuation bits are binary weighted, with the least significant bit (LSB) 1 dB. States are selected by 3 positive-voltage control inputs. DC blocking capacitors are required at each RF port. Both RF ports are absorptive. The QFN-16 package is lead (Pb)-free and complies with current RoHS requirements. The attenuator can operate over the temperature range of -40 °C to +85 °C. RF Input/Output NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.
