[2] Circuit Board Material: Rogers 4350
[3] Choose values of R2 & R4 between 4.3 and 20 Ohms for best
noise performance
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.
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.
