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

GND
RF IN
RF input pin. This pin is not internally 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.
4
VCC
Supply connection. This pin should be bypassed with a suitable capac-
itor(s).
RF output and bias pin. The output impedance of this pin is internally
matched to 50
using resistive feedback. Because DC biasing is
present on this pin, a DC blocking capacitor should be used in most
applications (see application schematic).
