General Description
The HMC494LP3 is a low noise Divide-by-8
Static Divider utilizing InGaP GaAs HBT technol-
ogy packaged in a leadless 3x3 mm QFN surface
mount plastic package. This device operates from
DC (with a square wave input) to 18 GHz input
frequency from a single +5.0V DC supply. The
low additive SSB phase noise of -150 dBc/Hz at
100 kHz offset helps the user maintain excellent
system noise performance.
