Description
RF input pin. This pin requires the use of an external DC blocking capacitor
chosen for the frequency of operation.
Connection to ground. Use via holes for best performance to reduce lead
inductance. Place vias as close to ground leads as possible.
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 the bias network should be well
bypassed.
Same as Pin 2.
