Video equipment using broadband signals must solve the problem of matching with coaxial cables, and several cables cannot be connected in parallel at one output.
For the signal distribution method, you can add several matching 75 ohm resistors at the output of the low output impedance amplifier or like this circuit, add a wide buffer amplifier for each channel.
Circuit working principleThis circuit uses the OP amplifier LM6361 for wideband video to perform inverse amplification. This amplifier can work stably even if the amplification factor is 1. The variable resistor VR1 of the amplifier A1 can be used to adjust the amplification factor between 1 and 3.5.

The High Power Battery Pack is mainly used in various vehicles, ships, aircraft and other internal combustion engines, lighting, energy storage, uninterrupted power supply, mobile communication, portable electric tools, electric toys.there are some differences compared with other normal battery .
1.properties
High power Lithium Battery is a battery that powers a vehicle, usually compared to a small battery that powers a portable electronic device. And normal lithium battery is a kind of anode materials for lithium metal or lithium alloy, using nonaqueous electrolyte solution of a battery, and Rechargeable Battery lithium ion battery and lithium ion polymer battery is not the same
2.discharge power
a 4200 mah high power lithium battery can discharge all power in just a few minutes, but normal lithium battery could not do that completely, so normal lithium battery discharge ability cannot be compared with the high power lithium batteries entirely. The biggest difference between high power lithium battery and onormal lithium battery lies in its high discharge power and higher energy. Since high power lithium-ion batteries are mainly used for automotive energy supply, they have higher discharge power than ordinary batteries.
3.High Power Battery pack can discharge at higher instantaneous current than normal Lithium Battery Pack
