General Description
Features
Functional Diagram
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.
Ultra Low SSB Phase Noise: -150 dBc/Hz
