Signal input pin. A internal matching
circuit, configured with resisters, enables

A multi-negative feedback circuit is
designed to cancel the deviations of h
and resistance.
This pin must be coupled to signal source
with capacitor for DC cut.
Ground pin. This pin should be
connected to system ground with
minimum inductance. Ground pattern on
the board should be formed as widely as
possible. All the ground pins must be
connected together with wide ground
pattern to decrease impedance
difference.
Signal output pin. The inductor must be
attached between V
supply current to the internal output
transistors.
Power supply pin, which biases the
internal input transistors.
This pin should be externally equipped
with bypass capacitor to minimize its
impedance.
