Description
Ground connection. Keep traces physically short and connect immedi-
ately to ground plane for best performance.
Same as pin 1.
Interface Schematic

GND
RF IN
RF input pin. This pin is not externally DC blocked and thus requires an
external blocking capacitor suitable for the frequency of operation. The
input impedance of this pin is internally matched to 50
using resistive
feedback.

GND
RF OUT
Same as pin 1.
RF output and bias pin. The input impedance of this pin is internally
matched to 50
using resistive feedback. 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.
See pin 3 schematic.
