ATTENUATOR, 0.7 - 3.7 GHz
Evaluation Circuit Board

* R2 - R6 = 100 Ohm.
These resistors are optional
and may be used to enhance
decoupling of the RF path
from the control inputs.
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 and exposed ground paddle should be connected directly to the ground
plane similar to that shown below. A sufficient number of VIA holes should be used to connect the top and bottom
ground planes. The evaluation circuit board as shown is available from Hittite Microwave Corporation upon request.
