DATA SHEET ACA0862B and ACA0862D: 1 GHz CATV Line Amplifier MMIC Applications 50 to 1000 MHz 75 amplifier HFC distribution systems CATV head-end equipment CATV line amplifier Features 1 GHz specified performance Flat gain Very low distortion Excellent input/output match Low DC power consumption Good RF stability with high VSWR load conditions Description Surface-mount package compatible with automatic assembly The ACA0862 family of surface-mount monolithic GaAs RF Linear Low cost Amplifiers has been developed to replace, in new designs, the standard CATV Hybrid amplifiers currently in use. The ACA0862 Repeatability of monolithic fabrication can also replace the ACA0861 with the addition of tuning Meets Cenelec standard capacitors to the output (see Figure 3). The MMICs consist of two RoHS-compliant packaging parallel amplifiers, each with 12 dB gain. The amplifiers are optimized for exceptionally low distortion and noise figure while providing flat gain and excellent input and output return loss. The TM ACA0862B and ACA0862D are optimized for different output Skyworks Green products are compliant with powers, and can be used separately or cascaded to support a all applicable legislation and are halogen-free. variety of applications. A hybrid equivalent is formed when two For additional information, refer to Skyworks ACA0862 devices are cascaded between transmission line TM Denition of Green , document number baluns. For low-gain applications, a single ACA0862 can be used SQ04-0074. for higher-gain applications, more than two can be cascaded. See the ACA0861 application note for more information. A block diagram of the ACA0862 is shown in Figure 1. The device package and pinout are shown in Figure 2.
