Functional Diagram
General Description
the HMc494LP3 & HMc494LP3e are low noise
Divide-by-8 static Dividers utilizing inGaP GaAs
HBt technology packaged in leadless 3x3 mm qFn
surface mount plastic packages. this device operates
from Dc (with a square wave input) to 18 GHz input
frequency from a single +5v Dc supply. the low
additive ssB phase noise of -150 dBc/Hz at 100 kHz
offset helps the user maintain excellent system noise
performance.

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 con-
nected 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.
