Pin Function Description 1 RF IN Device 1. RF input pin. This pin requires the use of an external DC-blocking capacitor as shown in the schematic.,, GND Connection to ground. Use via holes for best performance to reduce lead inductance as close to ground leads as possible., 7 4 RF IN Device. RF input pin. This pin requires the use of an external DC-blocking capacitor as shown in the schematic. 5 RF OUT/VCC Device. RF output and bias pin. Bias should be supplied to this pin through an external series resistor and RF choke inductor. Because DC biasing is present on this pin, a DC-blocking capacitor should be used in most applications. The supply side of the bias network should be well bypassed. RF OUT/VCC Device 1. Same as pin 5. EPAD GND Exposed area on the bottom side of the package must be soldered to the ground plane of the board for optimum thermal and RF performance. Several vias should be located under the EPAD as shown in the recommended land pattern.
