nextraCOM TDR8130G - Bi-Directional Line Amplifier   Suitably used in bi-directional transmission (can be reserved) and signal equalization of multi-class trunk transmission or high-required distributive network. Adopt PHILIPS, MOTOROLA imported power doubler modules. Audio pre-amplifier is low-noise microwave tube push-pull amplifier to insure enough gain. It has 1 input and 2 outputs, and each connection has over-current protection. The output branch or distributiveness can be changed following it. Double-equalizer is used, so adjusting multi-class transmission flatness is simple and convenient. Attenuator and equalizer are plug-in, so customers can choose fixed or adjustable style. High-reliable switch power (or linear power) and strict waterproof and anti-thunder design insure steady durative work.Specifications:Forward TransmissionFrequency RangeMHz45~860Rated GaindB≥30Flatness In BanddB±1.0Rated Input LeveldBµV72Rated Output LeveldBµV102Gain Adjustable RangedBAdjustable: 0~15dB, Fixed: 3,6,9,12,15Slope Adjustable RangedBAdjustable: 0~24 dB, Fixed: 6,9,12,15,18Noise FiguredB≤±12Composite Triplee BeatdB60Composite Second OrderdB60Return LossdB≥12Reverse TransmissionFrequency RangeMHz5~65Flatness In BanddB≤±0.75Return LossdB≥14Rated GaindB0 or 20 selectedMAX Output LeveldBµV≥110Gain Adjustable RangedB0~15Slope Adjustable RangedB0~10General responsePower Voltage (50Hz)V60VThunder StrokeKV5 (10/700µS)Dimensionmm270x215x118 Caution:   a.In order to insure long-distance transmission flatness and low-frequency band carrier to noise ratio, fixed equal plug-in should be use correctly. The accuracy of frequency balanced plug-in is high, so usually it is no need to adjust class electric circuit if without appropriation standard instrument.   b.Must use the power with over-current protection.   c.When the installation finished, please examine over-current circumstance. If need not over-current protection circuit, must pull out the fuse in this circuit. You should examine if the load is a short circuit with a multimeter when you need over-current protection circuit.   d.Service: The product installed or maintained by professionals.
