These pins are DC coupled and matched to 50 Ohms.
Blocking capacitors are required.
The pins are not connected internally; however, all
data shown herein was measured with these pins
connected to RF/DC ground externally.
Package bottom has exposed metal paddle that must
be connected to PCB RF ground as well.

[2] Circuit Board Material: Rogers 4350
The circuit board used in the application should
be generated with proper RF circuit design tech-
niques. Signal lines at the RF port should have
50 Ohm impedance and the package ground leads
and backside ground slug should be connected
directly to the ground plane similar to that shown
above. The evaluation circuit board shown above is
available from Hittite Microwave Corporation upon
request.
Note: Pin J6 is unused and need not be connected.
