Description
The AF002N2-32 is a single control non-reflective 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 2 DC blocking capacitors (C BL) and 1 bypass capacitor (CBP ). Operating Characteristics at 25°C (0, -5 V) Parameter1 Frequency2 Min. Typ. Max.
