Function and applications
Internal equivalent circuit
1
INPUT
1.00
0.97
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.
4
OUTPUT
4.40
4.12
Signal output pin. A internal matching circuit,
configured with resistors, enables 50
:
connection over a wide band. This pin must
be coupled to next stage with capacitor for DC
cut.
6
V
CC
4.5 to 5.5
Power supply pin. This pin should be
externally equipped with bypass capacitor to
minimize ground impedance.
2
3
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.
Note
Pin voltage is measured at VCC = 5.0 V, Above:
