AF002N2-32
Features
s Single Voltage Control, Positive or
Negative Voltage
s Low Cost SOT-143 Package
s 15 dB Dynamic Range
s Non-Reflective
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 (CBL) and
1 bypass capacitor (CBP).
