HMC445LP4

SMT GaAs HBT MMIC x16 ACTIVE

FREQUENCY MULTIPLIER, 9.9 - 11.0 GHz OUTPUT

v01.0604

General Description

Features

Functional Diagram

Output Power: +7 dBm

Sub-Harmonic Suppression: >25 dBc

SSB Phase Noise: -130 dBc/Hz

Single Supply: 5V@ 78 mA

Typical Applications

Active Multiplier for X Band Applications:

• Fiber Optic

• Pt to Pt Radios

• Military Radar

The HMC445LP4 is an active miniature x16

frequency multiplier utilizing InGaP GaAs HBT

technology in a 4 mm x 4 mm leadless surface

mount package. Power output is +7 dBm typical

from a 5.0V supply voltage and varies little vs. input

power, temperature and supply voltage. Suppression

of undesired fundamental and sub-harmonics is

>25 dBc typical with respect to output signal level.

The low additive SSB phase noise of -130 dBc/Hz at

100 kHz offset helps the user maintain good system

noise performance. The HMC445LP4 is ideal for

use in LO multiplier chains allowing reduced parts

count vs. traditional approaches.
