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 (C
BP
).
