BGA3131 DOCSIS 3.1 upstream amplifier
●The BGA3131 is an upstream amplifier meeting the Data Over Cable Service Interface Specifications 3.1. It is designed for cable modems, CATV set top box and VoIP modem applications.
●It amplifies the modulated signals coming from the SoC to a defined power level at the F-connector towards the network.
●The device can handle signals between 5 MHz to 205 MHz. The BGA3131 provides 58 dB gain control range in 1 dB increments with high incremental accuracy. Its maximum gain setting delivers 37 dB voltage gain and a superior linear performance.
●It supports the DOCSIS 3.1 output power levels of 68dBmV (RMS) while meeting the stringent ACLR requirements.
●The current consumption and gain settings are controlled through a digital serial interface (SPI).
●The BGA3131 is housed in 20 pins 5 mm x 5 mm leadless HVQFN package and don't need additional heatsink.
