Description
Signal input pin. An internal matching circuit, configured
with resistors, enables a 50
Ω
connection over a wide
band. A multi-feedback circuit is designed to cancel the
deviations of h
FE
and resistance. This pin must be
coupled to the signal source with a blocking capacitor.
Signal output pin. This output is designed as an open
collector for Darlington transistors. Connect an inductor
between this pin and V
CC
pin to supply current to the
internal output transistors. The inductor should be
selected for high frequency use and small DC resistance.
Power supply pin. This pin should be externally
equipped with a bypass capacitor to minimize ground
impedance.
Ground pins of internal input stage. Form a ground
pattern as wide as possible to minimize ground
impedance.
Ground pins of internal output stage. All the ground pins
including pins 6 and 7 must be connected together with
a wide ground pattern to decrease impedance difference.
