General Description
The HMC438MS8G & HMC438MS8GE are low noise
Divide-by-5 Static Dividers utilizing InGaP GaAs
HBT technology in low cost 8 lead surface mount
plastic packages. This device operates from DC
(with a square wave input) to 7 GHz input frequency
from a single +5V DC supply. The low additive SSB
phase noise of -153 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 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
Analog Devices, upon request. This evaluation
board is designed for single ended input testing. J2
and J3 provide differential output signals.
