Function and Applications
Internal Equivalent Circuit
1
INPUT
–
1.16
Signal input pin. A internal
matching circuit, configured with
resistors, enables 50
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
signal source with capacitor for
DC cut.

OUTPUT
Voltage
as same
as V
CC
through
external
inductor
–
Signal output pin. The inductor
must be attached between V
CC
and output pins to supply
current to the internal output
transistors.
6
V
CC
4.5 to 5.5
–
Power supply pin, which biases
the internal input transistor.
This pin should be externally
equipped with bypass capacitor
to minimize its impedance.

5
GND
0
–
Ground pin. This pin should be
connected to system ground
with minimum inductance.
Ground pattern on the board
should be formed as wide as
possible.
All the ground pins must be
connected together with wide
ground pattern to decrease
impedance difference.
