General Description
Functional Diagram
The HMC432(E) is a low noise Divide-by-2 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 -148 dBc/Hz at 100 kHz offset
helps the user maintain good system noise
performance.
