Function and Applications
Signal input pin. A internal
matching circuit, configured with
resisters, enables 50 Ω connec-
tion over a wide band. This pin
must be coupled to signal source
with capacitor for DC cut.

All the ground pins must be con-
nected together with wide ground
pattern to decrease impedance
