These pins and package bottom

must be connected to RF/DC ground.

The pins are not connected internally; however, all data

shown herein was measured with these pins connected to

RF/DC ground externally.

These pins are DC coupled and matched to 50 Ohms. Blocking

capacitors are required if RF line potential is not equal to 0V.
