Evaluation PCB
10
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 backside ground slug 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.

List of Material
Note: The evaluation PCB for the HMC440QS16G
contains 10K Ohm pull up resistors for each of the
five control inputs A0 through A4. Programming the 31
distinct division ratios consists of installing or removing
jumpers S1 through S5, as shown below.
