Description
Ground connection of the LO phase shift network. This pin should be
connected directly to the ground plane.
Ground connection for other circuits. Keep traces short and connect to
ground plane immediately.
Same as pin 11.
Ground connection for the RF output stage. A good ground connection
is especially important at this pin to avoid interference with other cir-
cuits.
50
capacitor is recommended.
