RF input pin. This pin should be
coupled with capacitor (eg 1000 pF)
for DC cut. Input return loss can be
improved with external impedance
matching circuit.

minimum inductance. Ground patt-
ern on the board should be formed
as wide as possible. Ground pins
must be connected together with
wide ground pattern to decrease
impedance difference.
−
RF output pin. This pin is designed
as open collector of high impedance.
This pin must be externally equipped
with matching circuits.
