Pin Function Description

Interface Schematic

1

GND

Ground connection. For best performance, keep traces physically short

and connect immediately to ground plane.

2

GND

Same as pin 1.

3

RF IN

RF input pin. This pin is internally DC-blocked and thus does not

require an external blocking capacitor. The input impedance of this pin

is internally matched to 50Ω using resistive feedback.

VCC

300Ω

RF OUT

VCC

Supply connection. Generally, there is no need for an external bypass See pin 3 schematic.

capacitor.

5

RF OUT RF output pin. The output impedance of this pin is internally matched to See pin 3 schematic.
