Functional Diagram
General Description
The HMC426MS8 is a low noise Divide-by-4
Static Divider utilizing SiGe technology in an 8
lead surface mount plastic package. This device
operates from DC (with a square wave input) to
4.0 GHz input frequency while operating from a
single +3V supply at only 13 mA. The low additive SSB phase noise of -146 dBc/Hz at 100 kHz
offset helps the user maintain excellent system
noise performance.

107620 Eval Board
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
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. This evaluation board is designed for
single ended input and output testing.
* Circuit Board Material: Rogers 4350
