Functional Diagram

General Description

The HMC438MS8G & HMC438MS8GE are low noise

Divide-by-5 Static Dividers utilizing InGaP GaAs HBT

technology in low cost 8 lead surface mount plas-

tic packages. 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.

Evaluation PCB

List of Materials for Evaluation PCB 105786 ^[1]

The circuit board used in the ﬁnal application should

use RF circuit design techniques. Signal lines

should have 50 ohm impedance while the package

ground leads and backside ground slug 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. This evaluation board is

designed for single ended input testing. J2 and J3

provide differential output signals.
