The ADA4303-2 is a 75 Ω, two-output active splitter for use in applications where a lossless split is required. It features excellent frequency response and low noise characteristics, making it ideal for CATV applications.
The ADA4303-2 active splitter provides a single‑ended 75 Ω input and two 75 Ω outputs with 3 dB of gain, low noise figure and high isolation, making it suitable for set‑top boxes, home gateways and CATV distribution systems. It is offered in a 12‑lead LFCSP package and operates from –40 °C to +85 °C.
The document includes functional block diagrams, pin descriptions, absolute maximum ratings, thermal resistance data, typical performance curves, evaluation‑board details and layout recommendations for optimal impedance matching and power supply decoupling.
