Mini Bidirectional Outdoor Field CATV Amplifier,(DT-CBA-1003KE) is a high gain high output bidirectional
amplifier,It is suitable to the 1GHz CATV bidirectional cable transmission network,Forward Path:(Operating
Frequency:45/87-862/1003 MHz,Highest Gain:≥38dB,C/CTB:≥66dB,C/CSO:≥64dB.),Return Path:(Operating Frequency:5~30/65
MHz,Highest Gain:≥24dB,Carrier second order intermodulation ration:≥52dB,Operating Voltage :AC150~265V or AC 35~90V(50Hz),
Dimension:220mm x :205mm x 65mm.
★Features
⊙1003MHz bandwidth design.
⊙It is more convenient to debug because of the plug-in duplex filter, equalizer, attenuator, output tap and the scientific and reasonable on-line detection ports.
⊙Forward path: The pre-stage adopts GaAs MMIC, output stage adopts the newest imported high index power doubly module, achieve high output level, low distortion and high SNR.
⊙The equipment can long time continuous work steadily under outdoor bad environmental condition. Because of the aluminum waterproof housing, high reliability switching power supply and strict lightning protection system.
