Overview
The RCA D903 in-line satellite amplifier is designed to amplify weak satellite and cable TV signals in the 950–2050 MHz frequency band. This amplifier is designed for in-line boosting of weak satellite signals and amplifies the signal to get the best picture quality when an installation requires long cable runs. The unit delivers a gain range of 13–18 dB with a maximum output of 110 dBµV across the 950–2050 MHz band. The D903 is a legacy satellite (DBS) component suitable for systems requiring signal conditioning over extended coaxial cable distances.
Key Features
- Frequency range: 950–2050 MHz (legacy DBS/legacy satellite downconverted band)
- Gain: 13–18 dB with maximum output 110 dBµV
- Low noise figure for clean signal amplification
- Compact, in-line design for easy installation between LNB and receiver
- Powers itself through the 13/18 volt supply from the DBS receiver — no external power required
- Ideal for long coaxial cable runs (typically >200 feet)

Typical Applications
The RCA D903 is used in satellite and cable TV installations where signal quality degrades over long cable runs. Common applications include:
- Extended cable runs from satellite dish to multiple receivers
- Signal conditioning for weak incoming satellite signals
- Legacy DBS (Direct Broadcast Satellite) system upgrades
- Residential satellite TV distribution systems
- Applications requiring 13–18 dB signal gain in the 950–2050 MHz band
