Functional Diagram
General Description
The HMC361S8G & HMC361S8GE are low noise
Divide-by-2 Static Dividers with InGaP GaAs HBT
technology in 8 lead surface mount plastic packages.
This device operates from DC (with a square wave
input) to 10 GHz input frequency with a single +5V
DC supply. The low additive SSB phase noise of -148
dBc/Hz at 100 kHz offset helps the user maintain good
system noise performance.

[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
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.
