1 VBIAS Internal DC Bias. This pin should be connected to VPOS through the R1 resistor. 2 RFIN RF Input. This is the input to the LNA. 3, 4, 5, 6 NC No Connection. No internal connection. 7 RFOUT RF Output. 8 VPOS 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. 9 (EPAD) Exposed Pad (EPAD) GND. Connect the exposed pad to a low impedance ground plane. Rev.
