HMC438MS8G

SMT GaAs HBT MMIC

DIVIDE-BY-5, DC - 7.0 GHz

General Description

Features

Functional Diagram

The HMC438MS8G is a low noise Divide-by-5 Static

Divider utilizing InGaP GaAs HBT technology in a

low cost 8 lead surface mount plastic package. This

device operates from DC (with a square wave input)

to 7.0 GHz input frequency from a single +5.0V 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 @100KHz

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, Pt. - Pt. & VSAT Radios

• 802.11a & HiperLAN WLAN

• Fiber Optic

• Cellular / 3G Infrastructure

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