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.
Ground pin. This pin should be
connected to system ground with
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.
Supply voltage pin.
This pin must be equipped with
bypass capacitor (eg 1000 pF)
to minimize its RF impedance.
Gain control pin. The relation
between product number and control
performance is shown below;
