Signal Input pin. A internal
matching circuit, configured
with resistors, enables 50 Ω
impedance connection over a
wide band. This pin must be
coupled to signal source with
capacitor for DC blocking.
Signal output pin. The inductor
must be connected between
pin VCC and OUT for Output TR
BIAS and output choke. A
internal matching circuit,
configured with resistors,
enables 50 Ω impedance
connection over a wide band.
This pin must be coupled to
next stage input with capacitor
for DC blocking.
DC power supply pin. This pin
should be externally connected
to bypass capacitor to minimize
ground impedance.
Ground pins. This pins should
be connected to system ground
with minimum inductance.
All the ground pins must be
connected common with wide
ground pattern to minimized
impedance difference
