Pin Function Description

Interface Schematic

10

GND1

Ground connection of the LO phase shift network. This pin should be

connected directly to the ground plane.

11

GND

Ground connection for other circuits. Keep traces short and connect to

ground plane immediately.

12

GND

Same as pin 11.

13

GND2

Ground connection for the RF output stage. A good ground connection

is especially important at this pin to avoid interference with other cir-

cuits.

14

RF OUT 50Ω output. This pin carries a DC voltage, and an external blocking

capacitor is recommended.
