HMC698LP5(E) Synthesizer

116106 Eval Board

[1] Reference this number when ordering complete evaluation PCB

[2] Circuit Board Material: Rogers 4350

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.

Note: The evaluation PCB for the HMC698LP5 contains 10K

Ohm pull up resistors for each of the 9 control inputs. Pro-

gramming the 251 distinct division ratios consists of install-

ing or removing jumpers N0 through N5 and S0, S1.

Note: 0 = Jumper Installed.

1 = Jumper Not Installed.
