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

(see Programming Truth Table)
Note: 0 = Jumper Installed.
1 = Jumper Not Installed.
Note: The evaluation PCB for the HMC698LP5 contains
10K Ohm pull up resistors for each of the 9 control inputs.
Programming the 251 distinct division ratios consists of
installing or removing jumpers N0 through N5 and S0, S1.
