SPA1118Z Recommended Land Pattern Branding Diagram Pin Function Description 1VCC Supply voltage for the active bias network. Bypassing in the appropriate location as shown on the application schematic is required for optimum RF performance. 2VBIAS Bias control pin for the active bias network. Device current is set by the current into this pin. Recommended configura- tion is shown in the application schematic. Bypassing in the appropriate location as shown on the application schematic is required for optimum RF performance. 3RF IN RF input pin. This pin requires the use of an external DC-blocking capacitor chosen for the frequency of operation. 4, 5 NC No connection. 6RF OUT/VCC RF output and bias pin. Bias should be supplied to this pin through an external RF choke. 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. An output matching network is necessary for optimum performance. 7, 8 NC No connection. EPAD GND Exposed area on the bottom side of the package needs to be soldered to the ground plane of the board for thermal and RF performance. Several vias should be located under the EPAD as shown in the recommended land pattern.
