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 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 50Ω using resistive

feedback.

RF OUT

RF IN

4

GND

Same as pin 1.

5

RF OUT RF output and bias pin. The input impedance of this pin is internally See pin 3 schematic.

matched to 50Ω 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.
