General Description
The HMC434 is a low noise Divide-by-8 Static
Divider utilizing InGaP GaAs HBT technology
in an ultra small surface mount SOT26 plastic
package. 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.
