Description:
The QRAM750 is a 750 MHz rack-mount amplifier designed for the modern headend. These 3.5 x 19-inch rack-mount amplifiers provide power-doubled, quadra-power and 750 or 870 MHz GaAs FET Hybrid RF output technology. Where 550 MHz is satisfactory, our QRAM550 amplifier offers similar RF output configurations at a lower total cost. Front panel -20 dB test points simplify the setup process. Regardless of the application, laser driver or headend post amplifier, virtual transparency may be achieved.
To accommodate wide ranges of signal conditions, plug-in input pads, plug-in input equalizers, interstage gain controls and interstage tilt controls have been provided in the QRAM design. For QRAM 550, 750 & 860 MHz, an optional output diplex filter may be inserted. A separate port has been provided for retrieving the 5 MHz to 40 MHz return path signals.
The optional internal splitters provide two or four independent output ports which can be set to different signal levels w/SXP pads (not for 870 MHz splitters). |
