Signal input pin.
A internal matching circuit, configured with resistors, enables 50
connection over a wide band.
A multi-feedback circuits is designed to cancel the deviations of h
FE
and
resistance.
This pin must be coupled to signal source with capacitor for DC cut.

Power suplly pin.
Witch biases the internal input transistor. This pin should be externally
equipped with bypass capacitor to minimize its impedance.

–
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.
–
Signal output pin.
The inductor must be attached between V
CC
and output pins to supply
current to the internal output transistors.
Function and Applications
