Amplifier output pin. This pin is an open-collector output. It must be biased to VCC through a choke or matching inductor. This pin is typically matched to 50Ω with a shunt bias/matching inductor and series blocking/matching capacitor. Refer to application schematics. Ground connection. Ground connection. This pin is used to control the bias current. An external resistor may be used to set the bias current for any VPD voltage. Allows for trade-offs between IP3 versus noise figure and TMAX.
