General Description
The HMC433(E) is a low noise Divide-by-4 Static
Divider 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 GHz input frequency with a single +3V 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.
