Functional Diagram  

General Description  

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.

Evaluation PCB  

List of Materials for Evaluation PCB 104631

[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.
