Functional Diagram
General Description
The HMC434 & HMC434E are low noise Divide-by-8
Static Dividers utilizing InGaP GaAs HBT technology
in ultra small surface mount SOT26 plastic packages.
This device operates from DC (with a square wave
input) to 8.0 GHz input frequency with a single +3.0V
DC supply. Single-ended inputs and outputs reduce
component count and cost. The low additive SSB
phase noise of -150 dBc/Hz at 100 kHz offset helps
the user maintain good system noise performance.

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 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.
