DIVIDE-BY-2, DC - 10 GHz
General Description
Features
Functional Diagram
The HMC361S8G & HMC361S8GE are low noise
divide-by-2 static dividers with InGaP GaAs HBT
technology in 8 lead surface mount plastic pack-
ages. This device operates from DC (with a square
wave input) to 10 GHz input frequency with a single
+5V DC supply. The low additive SSB phase noise of
-148 dBc/Hz at 100 kHz offset helps the user maintain
good system noise performance.
Ultra low SSB phase noise: -148 dBc/Hz
Wide bandwidth
Output power: 3 dBm
Single DC supply: +5V
S8G SMT package
Electrical Specications, 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

The circuit board used in the application should use
RF circuit design techniques. Signal lines should
have 50 Ω impedance while the package ground
leads and backside ground slug should be con-
nected 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.
