General Description

Features

Functional Diagram

The HMC438MS8G & HMC438MS8GE are low noise

Divide-by-5 Static Dividers utilizing InGaP GaAs

HBT technology in low cost 8 lead surface mount

plastic packages. This device operates from DC

(with a square wave input) to 7 GHz input frequency

from a single +5V DC supply. The low additive SSB

phase noise of -153 dBc/Hz at 100 kHz offset helps

the user maintain good system noise performance.

SSB Phase Noise: -153 dBc/Hz @100 kHz

Wide Bandwidth

Output Power: -1 dBm

Single DC Supply: +5V @ 80 mA

MS8G SMT Package

Typical Applications

Prescaler for DC to C Band PLL Applications:

• UNII, Point-to-Point & VSAT Radios

• 802.11a & HiperLAN WLAN

• Fiber Optic

• Cellular / 3G Infrastructure

1. Divider will operate down to DC for square-wave input signal.
