Pin Name
Voltage
Function and Applications
No.
(V)
1
INPUT
Signal input pin. A internal matching
circuit, configured with resisters, enables
50
connection over a wide band.
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.
2
GND
0
Ground pin. This pin should be
3
connected to system ground with
4
minimum inductance. Ground pattern on
6
the board should be formed as widely as
7
possible. All the ground pins must be
connected together with wide ground
pattern to decrease impedance
difference.

OUTPUT
Voltage
Signal output pin. The inductor must be

V
4.5 to 5.5
Power supply pin, which biases the
CC
internal input transistors.
This pin should be externally equipped
with bypass capacitor to minimize its
impedance.
