Package bottom has an exposed metal paddle that

must also be RF & DC grounded.

RFOUT

RF output (AC coupled)

The circuit board used in the application should

use RF circuit design techniques. Signal lines

should have 50 Ohm impedance while the package

ground leads and exposed ground paddle should

be connected directly to the ground plane similar

to that shown. A sufficient number of via holes

should be used to connect the top and bottom

ground planes. The evaluation circuit board shown

is available from Hittite upon request.
