At the 2017 Mobile World Congress, MaxLinear announced a baseband system on chip (SoC) for broadband wireless transmission systems. The MxL85110 is a full duplex, single carrier, FDD modem that provides a comprehensive processing chain from the various user IP interfaces to the analog baseband signals, including analog-to-digital and digital-to-analog converters. The functionality provides a flexible baseband solution that meets the demands of fronthaul and backhaul networks and supports both the all outdoor unit (AODU) and pure IP transport implementations for 4G and 5G cellular networks.

The MxL85110 handles 10 Gbps bit rates in transmit and receive — baud rates to 1600 Mbaud — channel-spacing between 50 MHz and 2 GHz, modulation rates from binary phase-shift keying (BPSK) to 1024-QAM and high spectral efficiency for multiple-input-multiple-output (MIMO) transceivers and cross polarization interference cancellation (XPIC).

As operators seek to expand the bandwidth in fronthaul and backhaul networks, the millimeter spectrum, such as V- and E-Band, is attractive because of the larger blocks of spectrum and lower licensing costs. The wideband MxL85110 enables operators to take advantage of these bands.

The MxL85110 is available now. To obtain more information, email
