Description
The AF002N2-32 is a single control nonreflective IC FET VVA ideal for AGC applications. Its low DC drain characteristic and size make it suitable for PCS and portable cellular markets. A positive control voltage may be used by adding two DC blocking capacitors (CBL) and one bypass capacitor (CBP).
VS 10 k CBP GND External components for positive voltage operation only. CBL = 100 pF.
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.
