RF input pin.
This pin should be coupled with
capacitor (example 100 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 pa- ttern 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 de-signed 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 (example 1 000
pF) to minimize its RF impedance.
Gain control pin.
