HMC447LC3

v04.0514

SMT GaAs HBT MMIC

DIVIDE-BY-4, 10 - 26 GHz

General Description

Features

Functional Diagram

The HMC447LC3 is a low noise Divide-by-4

Regenerative Divider utilizing InGaP GaAs HBT

technology. This wideband divider operates with input

frequencies from 10 to 26 GHz, and accepts a very wide

range of input power levels. THe HMC447LC3 exhibits

a very low SSB Phase Noise of -150 dBc/Hz at 100 kHz

offset, making it ideal for use in high frequency Phase

Locked Loops (PLL), and in Local Oscillator (LO)

distribution applications where fundamental and

divided LO frequencies are required within a

system. This versatile divider consumes only 96 mA

from a single positive supply of +5V, and delivers

very flat output power across the rated bandwidth.

The HMC447LC3 is housed in a RoHS compliant,

3x3 mm leadless SMT package with an exposed

ground paddle.
