General Description

Features

Functional Diagram

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.

ultra Low ssB Phase noise: -150 dBc/Hz

very Wide Bandwidth

output Power: -4 dBm

single Dc supply: +5v

16 Lead 3x3mm qFn Package: 9 mm²

Typical Applications

Prescaler for Dc to 18 GHz PLL Applications:

• Point-to-Point / Multi-Point Radios

• VSAT Radios

• Fiber Optic

• Test Equipment

• Military
