* R2 - R6= 100 Ohm.
These resistors are optional
and may be used to enhance
decoupling of the RF path
from the control inputs.

Digital Attenuators
The circuit board used in the final application should
use RF circuit design techniques. Signal lines should
have 50 ohm impedance while the package ground
leads 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.
