The Johansson 9604 is a SAT line amplifier built for satellite signal distribution. It amplifies the intermediate frequency output from an LNB throughout a coaxial distribution network, maintaining signal integrity across the full satellite band.

With a noise figure of 4 dB and a maximum output level of 110 dBµV, it is suited for residential and small commercial satellite installations where signal strength needs to be maintained over longer cable runs or across multiple splitters.

Key Features

• Full SAT band coverage: 950–2150 MHz
• Variable gain: 13 dB at 950 MHz, 18 dB at 2150 MHz
• Maximum output level of 110 dBµV
• DC power pass up to 500 mA for LNB powering
• Powered via coaxial cable: 13–18 V / 30 mA

Product Benefits

• Compensates for signal loss on long cable runs or after splitters in SAT distribution
• Higher gain at the upper end of the band offsets the greater cable attenuation at higher frequencies
• DC pass capability allows the LNB to be powered through the same coaxial cable without a separate power feed
• Low current draw (30 mA) makes it easy to integrate into existing system power budgets

Technical Specifications

• Frequency Range: 950–2150 MHz
• Gain: 13 dB (at 950 MHz) / 18 dB (at 2150 MHz)
• Noise Figure: 4 dB
• Max. Output Level: 110 dBµV
• Power Supply: 13–18 V / 30 mA (via coaxial)
• DC Power Pass: 500 mA max

Why You'll Love It

• Compact inline design fits easily into existing coaxial runs without additional hardware
• Passive DC pass eliminates the need for a separate power injector for the LNB
• Johansson's professional-grade build ensures consistent performance over time
