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 h
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.
