The APS3625 active splitter accepts an RF input in the 50 MHz to 1.0 GHz frequency range and provides five RF outputs with minimal degradation in signal quality. The single-package surface mount device amplifies the input signals using highly linear, low noise amplification stages, and couples the amplified signal to five separate output paths to drive video tuner(s), a DOCSIS tuner(s), or other in-band inputs. The device provides one by-pass output to maintain a connection when the power is lost, which is intended for critical signals such as a digital voice phone. The overall linearity of each tuner path is maintained across the entire operating frequency range, ensuring low distortion effects on each output signal.
Requiring a single +3.3 Volt supply, the active splitter design is implemented using the GaAs MESFET process. The small surface mount QFN packaging makes this device ideal for use in home gateways and multiple-tuner set-top boxes, supporting multiple video outputs, and/or DOCSIS 3.0 and IP phones.
Please note: APS3625 is being discontinued and is not recommended for new designs.
