    INTRODUCTION

    The" J" seriesof line extendersoffers both

    conventional and power doubling tech-nologies.

    TheJLX-C usesthe latestgenerationof hybridpush-pulltechnologyfor 450 MHzoperation.The JLX-C is intended for use as a typicalfeederlineextender.JLX-C hasincreasedgainfor more economical system design andincludesa highlyefficientswitchmodepowersupplyfor minimumpowerconsumption.

    TheJLX-P line extendersuseadvancedpowerdoubling hybrid technology to provideimproveddistortionperformanceat highout-put levels.Thesepowerdoublingline exten-ders offer high gain performancewith lowpower requirements through the use of ahighlyefficientswitchingpowersupply.

    JLX-* FEATURES

    "J" seriesline extenderssupport60Vpower-ing at input levels as low as 38 volts. Surgearrestors,ModelXO-36,comeinstalledin all Jserieslineextenders.

    Power passingis accomplishedthrough useof CBJ-5circuitbreakersor thealternativeCFJ-

    7A 7 ampfuse.TheCTF-JLXis usedfor thermalcompensationandcanbe utilizedpre-stageorinter-stageto allow for minimizationof noisefigureor distortion,as requiredbyapplication.Theoptionalaccessoriesareorderedseparately.
