HMC494LP3
SMT GaAs HBT MMIC
DIVIDE-BY-8, DC - 18 GHz
Features
Ultra Low SSB Phase Noise: -150 dBc/Hz
Very Wide Bandwidth
Output Power: -4 dBm
Single DC Supply: +5V
3 x 3 x 1 mm QFN Package
General Description
The HMC494LP3 is a low noise Divide-by-8
Static Divider utilizing InGaP GaAs HBT technology 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.
