A DC blocking capacitor suitable for the frequency of operation should be used. RF IN To Bias Circuit RF OUT Interface Schematic 3 4 5 6 7 8 GND GND GND GND GND RF OUT Ground connection. Ground connection. Ground connection. Ground connection. Ground connection. 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 50 Ω 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.
