GND1

Ground connection. See evaluation board schematic notes.

3

PD

Power down pin. This pin serves as the interstage for the 2-stage LNA.

An inductor is required to pull pin 3 to VCC (see application schematic).

If desired, this voltage can be lowered to trade off IP3 versus ICC,TOTAL.

RF OUT Amplifier Output pin. This pin is an open-collector output. It must be

biased to either VCC or pin 4 through a choke or matching inductor.

This pin is typically matched to 50Ω with a shunt bias/matching induc-

tor and series blocking/matching capacitor. Refer to application sche-

matics.
