GaN-Based CATV Components

RF Micro Devices,Inc.'s RFPD2650 is a galliumnitride-based hybrid power doubler amplifier delivers low distortionperformance with the flexibility to optimize for supply current or energyconsumption. The RFPD2650 hybrid power doubler amplifier module is specificallydesigned for CATV infrastructure applications including hybrid fiber coaxial(HFC) optical nodes.

The RFPD2650 supplies aminimum gain of 21 dB over the entire 45-1003 MHz frequency range. It candeliver up to 20 percent power or energy savings with no performance penalty inHFC networks, or it can be configured to provide 3dB higher distortion levelperformance with the same power consumption. With this blend of performanceattributes, the RFPD2650 enables MSO system designers to select eitherindustry-leading or energy saving ("green") performance.

The RFPD2650 leverages GaNHEMT and GaAs pHEMT technology to enable longer range transmission. Maximumcurrent is 450mA, and current consumption can be reduced dramatically to lessthan 370mA for applications requiring reduced distortion performance.Programmed to match the distortion level of competitive devices, RFMD's RFPD2650delivers two watts of power consumption savings.
