The single-package surface mount device amplifies the input using highly linear, low noise amplification stages, and couples the amplified signal to three separate output paths that each can drive either analog video, digital video or digital data tuners. The APS3623 offers a special frequency/gain profile, which compensates for inband signal attenuation caused by MoCA line filters. Requiring a single voltage supply of +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 multiple-tuner solutions.
