Pin Function Description
Interface Schematic
1
GND
Ground connection. Keep traces physically short and connect immedi-
ately to ground plane for best performance.
2
GND
Same as pin 1.
3
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 50Ω using resistive
feedback.
VCC
RF OUT
RF IN
4
4
VCC
Supply connection. This pin should be bypassed with a suitable capac-
itor(s).
5
RF OUT RF output and bias pin. The output impedance of this pin is internally See pin 3 schematic.
matched to 50Ω using resistive feedback. Because DC biasing is
present on this pin, a DC blocking capacitor should be used in most
applications (see application schematic).
