Description

Internal Equivalent Circuit

Signal input pin. An internal matching

circuit, configured with resistors, enables

50 Ω connection over a wide bandwidth.

A multi-feedback circuit is designed to

cancel the deviations of hFE and resistance.

This pin must be coupled to the signal source

with a blocking capacitor.

Signal output pin. An internal matching

circuit, configured with resistors, enables

50 Ω connection over a wide bandwidth.

This pin must be coupled to the output

load with a blocking capacitor.

Power supply pin. This pin should be

externally equipped with a bypass capacitor

to minimize ground 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 minimize impedance

difference.
