Exposed Pad (EPAD)
Internal DC Bias. This pin should be connected to VPOS through the R1 resistor.
GND. Connect the exposed pad to a low impedance ground plane.
Description
RF Input. This is the input to the LNA.
No Connection. No internal connection.
RF Output.
Supply Voltage. DC bias needs to be bypassed to ground using a low inductance capacitor. This pin is
also used for output matching. See the Basic Connections section.
