HMC321LP4

Hello,

 

The data sheet for the HMC321LP4 indicates that the paddle on the bottom of the device should be connected to ground. Do you have a suggestion for how many vias or how much contact area is required on the paddle for proper opperation? Is the paddle also used to pull heat from the device? We missed this on the initial board and I would like to rework it and perfom some testing while I'm waiting for a new board spin.

 

Thank.
