Functional Diagram General Description
The HMC492LP3 & HMC492LP3E are low noise
Divide-by-2 Static Dividers utilizing InGaP GaAs
HBT technology packaged in leadless 3x3 mm
QFN surface mount plastic packages. This device
operates from DC (with a square wave input) to
18 GHz input frequency from a single +5V DC supply.
The low additive SSB phase noise of -150 dBc/Hz
at 100 kHz offset helps the user maintain excellent
system noise performance.
