NXP high-gain power doublers CGD104x Upgrade to sustainable 1 GHz CATV networks NXP offers a choice of standard and high-output power doublers for 1 GHz CATV applications. These high performance GaAs devices make it easy for cable operators to extend their services to include HDTV, VoIP and digital simulcasting. Key features Ñ E xcellent linearity, stability, and reliability Ñ High power gain Ñ E xtremely low noise Ñ Silicon Nitride passivity Ñ GaAs HFET dies for high-end applications Ñ High-output power versions (CGD104xH) Key benefits Ñ Simple upgrade to 1 GHz capable networks Ñ Optimized heat management Ñ E xcellent temperature resistance Ñ Low total cost of ownership Ñ High ESD levels Ñ High power-stress capability Ñ Highly automated assembly Key applications Ñ Hybrid Fiber Coax (HFC) applications Ñ Line extenders Ñ Trunk amplifiers Ñ Fiber deep-optical-node (N+0/1/2) NXP’s latest CGD104x range of power doublers have been designed for 1 GHz ‘sustainable networks’. These high performance GaAs devices provide extended bandwidth and higher data rates, giving you the increased network capacity to deliver high-end services like HDTV, VoIP and digital simulcasting. The CGD1042 and CGD1044 are ideal for use in line extenders and trunk amplifiers, while their high-output variants (CGD1042H and CGD1044H) are primarily designed for use in fiber deep-optical-node applications (N+0/1/2), delivering the highest output power on the market today. Designed for durability and offering superior ruggedness, these 1 GHz solutions offer an extended temperature range, high power overstress capabilities and high ESD levels. The result is low cost of ownership. Using a GaAs HFET die process delivers high gain and high performance, along with lower current and better CTB and CSO ratings. The GaAs die is then inserted in a unique HVQFN package that is mounted on thermo vias which manage heat transfer to the heat sink. Temperature-control circuitry keeps the module’s high performance stable over a wide range of temperatures. Assembly is also fully automated, requiring almost no human intervention, so manufacturing costs are kept to a minimum while repeatability remains very high. Upcoming push-pull products New push-pulls, currently under development, will combine with the power doublers to service almost all modern HFC applications. The push-pull CGY1041 will deliver a gain of 21 dB, the CGY1043 a gain of 23 dB, the CGY1047 a gain of 27 dB.
