Function and Applications
Internal Equivalent Circuit
1
INPUT
0.8
Signal input pin. A internal
matching circuit, configured with
resistors, enables 50
connec-
tion over a wide band.
A multi-feedback circuit is de-
signed to cancel the deviations of
h
FE
and resistance.
This pin must be coupled to sig-
nal source with capacitor for DC
cut.
4
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 con-
nected together with wide ground
pattern to decrease impedance
difference.
Note
Pin voltage is measured at V
CC
= 5.0 V
