Function and Applications

Internal Equivalent Circuit

Signal input pin. A internal

matching circuit, configured with

resistors, enables 50 Ω

connection over a wide band.

A multi-feedback circuit is

designed to cancel the

deviations of hFE and resistance.

This pin must be coupled to

signal source with capacitor for

DC cut.

Signal output pin. The inductor

must be attached between VCC

and output pins to supply

current to the internal output

transistors.

–

Power supply pin, which 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.
