General Description
Functional Diagram
The HMC432 & HMC432E are low noise Divide-
by-2 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 -148 dBc/Hz at 100 kHz offset helps the
user maintain good system noise performance.
