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 at output power across the rated bandwidth.
The HMC447LC3 is housed in a RoHS compliant,
3x3 mm leadless SMT package with an exposed
ground paddle.

Evaluation PCB
List of Materials for Evaluation PCB 107928 [1]
The circuit board used in the nal application sho-
uld use RF circuit design techniques. Signal lines
should have 50 Ohm impedance while the package
ground leads and backside ground paddle should
be connected directly to the ground plane similar
to that shown. A sufficient number of via holes
should be used to connect the top and bottom
ground planes. The evaluation circuit board shown
is available from Hittite upon request.
