General Description
The HMC438MS8G is a low noise Divide-by-5 Static
Divider utilizing InGaP GaAs HBT technology in a
low cost 8 lead surface mount plastic package. This
device operates from DC (with a square wave input)
to 7.0 GHz input frequency from a single +5.0V DC
supply. The low additive SSB phase noise of -153
dBc/Hz at 100 kHz offset helps the user maintain
good system noise performance.

105697 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
and backside ground slug 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 testing. J2
and J3 provide differential output signals.
