Functional Diagram
General Description
The HMC364G8 is a low noise Divide-by-2 Static
Divider with InGaP GaAs HBT technology in an
8 lead glass/metal surface mount (hermetic)
package. This device operates from DC (with a
square wave input) to 13 GHz input frequency
with a single +5.0V DC supply. The low addi-
tive SSB phase noise of -145 dBc/Hz at 100 kHz
offset helps the user maintain good system noise
performance.

* 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 evalu-
ation board is designed for single ended input testing. J2
and J3 provide differential output signals.
