Signal input pin. A internal
matching circuit, configured with
resistors, enables 50 Ω connec-
tion 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 con-
nected together with wide ground
pattern to decrease impedance
defference.
Signal output pin. This pin is de-
signed as collector output. Due
to the high impedance output,
this pin should be externally
equipped with LC matching
circuit to next stage. For L, a
size 1005 chip in-ductor can be
chosen.
Power supply pin. This pin
should be externally equipped
with bypass capacitor to
minimize its inpedance.
