ETL Systems 4-Way Active RF Combiners
ETL Systems 4-way active RF combiners combine four RF inputs into one common output for satellite communications and RF systems, with model-specific frequency ranges of 850–2150 MHz, 850–2500 MHz, 50–2150 MHz, or 50–2800 MHz. Choose from 50 Ω or 75 Ω connector options and different DC/10 MHz reference pass/block arrangements to suit your installation.
Frequency Range: 850–2150 MHz, 850–2500 MHz, 50–2150 MHz, or 50–2800 MHz, depending on model
Configuration: 4-way active RF combiner
Combiner Ports: 4 inputs and 1 common output
Impedance: 50 Ω or 75 Ω, depending on connector option
RF Connectors: SMA, N-type, BNC, or F-type; availability varies by model
Power: External or inline DC bias; requirements vary by model
DC & 10 MHz Reference: Model-specific pass/block arrangements
Key Features
• Active RF signal combining from four inputs into one output
• High linearity and low amplitude imbalance
• Integrated voltage regulators for protection against supply rail fluctuations
• Selected models support DC and 10 MHz reference pass-through
