ETL Systems 8-Way Active RF Combiners
ETL Systems 8-way active RF combiners combine eight L-band RF inputs into one common output for satellite communications and RF systems across 850–2150 MHz. Choose from 50 Ω or 75 Ω connector options and model-specific DC/10 MHz reference arrangements, including a model with LNB bias injection on the common port.
Frequency Range: 850–2150 MHz
Configuration: 8-way active RF combiner
Combiner Ports: 8 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
LNB Bias: Common-port injection on COM08L1A-2246
Key Features
• Active L-band signal combining from eight 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
• Choice of DC-blocked, selective pass-through, and LNB bias configurations
