Signal input pin. A internal matching
circuit, configured with resistors, enables
50 Ω connection over a wide band. this
pin must be coupled to signal source with
capacitor for DC cut.
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.
Signal output pin. A internal matching
circuit, configured with resistors, enables
50 Ω connection over a wide band. This
pin must be coupled to next stage with
capacitor for DC cut.
Power supply pin. This pin should be
externally equipped with bypass capacity
to minimize ground impedance.
