Description
No internal connection; must be grounded on PCB
Input, matched to 50 ohms
No internal connection. Can be grounded or left open
Gate voltage. Bias network is required; see Application Circuit on page 11 as
an example.
Output, matched to 50 ohms
Drain voltage. Bias network is required; see Application Circuit on page 11 as
an example.
Backside Paddle. Multiple vias should be employed to minimize inductance
and thermal resistance; see Mounting Configuration on page 15 for suggested
footprint.
