HMC362S8G / 362S8GE
SMT GaAs HBT MMIC
DIVIDE-BY-4, DC - 12 GHz
General Description
Features
Functional Diagram
The HMC362S8G & HMC362S8GE are low noise
Divide-by-4 Static Dividers with InGaP GaAs HBT
technology in 8 lead surface mount plastic packages.
This device operates from DC (with a square wave
input) to 12 GHz input frequency with a single +5V
DC supply. The low additive SSB phase noise of -149
dBc/Hz at 100 kHz offset helps the user maintain good
system noise performance.
Ultra Low SSB Phase Noise: -149 dBc/Hz
Wide Bandwidth
Output Power: -6 dBm
Single DC Supply: +5V
S8G SMT Package
Electrical Speci cations, TA = +25° C, 50 Ohm System, Vcc = 5V
Typical Applications
Prescaler for DC to X Band PLL Applications:
• Satellite Communication Systems
• Fiber Optic
• Point-to-Point and Point-to-Multi-Point Radios
• VSAT

Evaluation PCB
List of Materials for Evaluation PCB 104631 [1]
The circuit board used in the nal 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.
