Overview
MXT-RA30-860RA Single module bi-directional amplifier, the former adopts GaAs MMIC amplification; the latter adopts GaAs module amplification. It is characterized by high output level, good in-band flatness and non-linearity index. Plug-in one-way tap or two-way splitter output, to operate conveniently. Two-way or two-way pre-reversed optional. This kind of amplifier is used to work in CATV trunk transmission network and distribution network.
Features
● 862MHz bandwidth.
● Adopts high gain push-pull or GaAs amplifier module to ensure high level and good SNR.
● The design of two-output can replace the mode of distribution or subdivision flexibly.
● Built-in modulated equalizer and modulated attenuator, convenient for debug.
● Plug-in (reserved) reverse module may open up reverse channel easily.
● External power pilot light, easy to observe the operating status.
● Die-cast aluminum housing, high-quality switching power supply and the effective lightning-proof measure.
