SMT GaAs HBT MMIC

DIVIDE-BY-2, DC - 18 GHz

General Description

Features

Functional Diagram

The HMC492LP3 & HMC492LP3E are low noise

Divide-by-2 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

3x3 mm QFN SMT Package

Typical Applications

Prescaler for DC to 18 GHz PLL Applications:

• Point-to-Point / Multi-Point Radios

• VSAT Radios

• Fiber Optic

• Test Equipment

• Military
