Functional Diagram
General Description
The HMC426MS8 & HMC426MS8E are low noise Divide-by-4 Static Dividers utilizing SiGe technology in 8 lead surface mount plastic packages. 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.

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.
