Functional Diagram
General Description
The HMC251MS8 is a low noise divide-by-2 GaAs
MMIC prescaler in an 8 lead surface mount MSOP
plastic package. This device operates from 3.0 to
6.5 GHz (input frequency) with a single +5.0 V DC
supply while drawing only 27 mA of current. The low
residual phase noise of this prescaler helps the user
maintain good system noise performance.
