Function
Description
GND
Connection to ground. For best
performance use via holes (as close to
ground leads as possible) to reduce lead
inductance.
GND Same as Pin 1
RF IN
RF input pin. This pin requires the use of an
external DC blocking capacitor chosen for
the frequency of operation.
GND Same as Pin 1
GND Same as Pin 1
RF OUT
RF output and bias pin. Bias should be
supplied to this pin through an external
series resistor and RF choke inductor.
Because DC biasing is present on this pin, a
DC blocking capacitor should be used in
most applications (see application
schematic). The supply side of this bias
network should be well bypassed.
