SMT SiGe MMIC
DIVIDE-BY-4, DC - 4.0 GHz
General Description
Features
Functional Diagram
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 addi-
tive SSB phase noise of -146 dBc/Hz at 100 kHz
offset helps the user maintain excellent system
noise performance.
Ultra Low SSB Phase Noise: -146 dBc/Hz
Wide Input Power Range: -15 to +10 dBm
Output Power: +3.5 dBm
Single DC Supply: +3V @ 13 mA

Evaluation PCB
List of Materials
The circuit board used in the fi nal 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 suffi cient number of via holes should
be used to connect the top and bottom ground planes.
The evaluation circuit board shown is available from Hit-
tite upon request. This evaluation board is designed for
single ended input and output testing.
