The singlepackage surface mount device amplifies the input using highly linear, low noise amplification stages, and couples the amplified signal to eight separate output paths that each can drive digital video tuners. The overall linearity of each path is maintained across the entire operating frequency range, ensuring low distortion effects on each output signal. Requiring a single voltage supply of either +3.3V or +5 V, the active splitter is manufactured using ANADIGICS' highly reliable GaAs MESFET process. The small surface mount QFN packaging makes this device ideal for use in today's set-top boxes, televisions and video tuner cards requiring multipletuner solutions.

Application circuits are available for other supply voltages. Contact ANADIGICS broadband engineering for more detail. 2) The BIAS pin is normally grounded for 3.3 V applications. However, the device linearity may be improved at VDD = 5 V by applying an external voltage on the pin, using a voltage divider circuit between VDD and GND. 3) L2 and C3 may be necessary for matching. The values are determined by the application, as needed.
