General
The Lambda Pro 45 is a dual output distribution amplifier for application in HFC networks.
The amplifier is equipped with new state of the art MESFET Gallium Arsenide hybrids to achieve
high output level and saturation factor, thus improving system performance and even reducing
power consumption. Additionally, a power factor corrector reduces AC-power in the network to
safe energy costs.
The amplifier is specially designed for combined channel load of both analogue (PAL) and digital
(QAM) signals allowing continuing operational levels when replacing analogue signals by digital
signals in future.
The Lambda Pro 45 has parallel circuits for both downstream and upstream equalization and attenuation to allow adjustment and exchange of plug-ins in the field without service interruption.
To simplify configuration and maintenance, the amplifier is equipped with fixed, switch able returnpath amplifier, diplex filters and output splitter. Plug-ins are only needed for adjusting input attenuation and slope.
An interstage slope jumper allows for sloped output level if required in a network concept.
Powering is possible both remotely through the RF input port or locally using the AMP fast-on AC
input port.
