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

• Point-to-Point Radios

• Military Radar

The

HMC445LP4

&

HMC445LP4E

are

active

miniature x16 frequency multipliers utilizing InGaP

GaAs HBT technology in 4x4 mm leadless surface

mount packages. Power output is +7 dBm typical

from a 5V 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 & HMC445LP4E are

ideal for use in LO multiplier chains allowing reduced

parts count vs. traditional approaches.
