APS3625

Five-way active power splitter

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.
