The JLX-Cuses the latest generation of hybrid push-pull technology for 450 MHz operation. The JLX-C is intended for use as a typical feeder line extender. JLX-C has increased gain for more economical system design and includes a highly efficient switch mode power supply for minimum power consumption. The JLX-P line extenders use advanced power doubling hybrid technology to provide improved distortion performance at high out- put levels. These power doubling line exten- ders offer high gain performance with low power requirements through the use of a highly efficient switching power supply. JLX-* FEATURES "J" series line extenders support 60V power- ing at input levels as low as 38 volts. Surge arrestors, Model XO-36, come installed in all J series line extenders. Power passing is accomplished through use of CBJ-5 circuit breakers or the alternative CFJ- 7A7 amp fuse. The CTF-JLXis used for thermal compensation and can be utilized pre-stage or inter-stage to allow for minimization of noise figure or distortion, as required by application. The optional accessories are ordered separately. All JLXseries line extenders use the EQ-* series of fixed equalizers, the same equalizers used in the Starline SX amplifier. Through the use of customer installed DF-* diplex filters, the JLX can be equally configured for a variety of split- band requirements. The DF-* diplex filters are also shared with the Starline SXamplifier. ~ GeneraL Instrument 5-17
