General Description
The HMC437MS8G & HMC437MS8GE are low noise
Divide-by-3 Static Dividers utilizing InGaP GaAs HBT
technology in low cost 8 lead surface mount plastic
packages. This device operates from DC (with a
square wave input) to 7.0 GHz input frequency from a
single +5.0V DC supply. The low additive SSB phase
noise of -153 dBc/Hz at 100 kHz offset helps the user
maintain good system noise performance.
