Nam e
Signal Input pin. A internal
m atching circuit, configured
with resistors, enables 50 Ω
im pedance connection over a
wide band. This pin m ust be
coupled to signal source with
capacitor for DC blocking.

Signal output pin. The inductor
m ust be connected between
pin VCC and OUT for Output TR
BIAS and output choke. A
internal m atching circuit,
configured with resistors,
enables 50 Ω im pedance
connection over a wide band.
This pin m ust be coupled to
next stage input with capacitor
for DC blocking.
