20 Gbps Millimeter Wave Modem for Front-Haul and Backhaul Applications

MaxLinear has introduced a new MxL85110 baseband system on-chip (SoC) for broadband wireless transmission systems. With exceptional 20 Gbps throughput, the MxL85110 provides a flexible solution that meets the evolving demands of front-haul and backhaul networks. It supports both an all outdoor unit (AODU) and pure IP transport implementations for 4G and 5G cellular networks.

The comprehensive functionality supported by the MxL85110 includes a complete processing chain, from various user IP interface technologies to analog baseband signals. It supports large channel-spacing spans of between 50 MHz and 2 GHz, modulation rates from binary phase-shift keying (BPSK) to 1024-QAM, and high spectral efficiency supporting multiple-input and multiple-out (MIMO) transceivers and cross pole interference cancellation (XPIC). Leveraging millimeter bands (V-Band and E-Band) has emerged as an attractive option due to larger blocks of available spectrum and lower licensing costs and the wideband MxL85110 enables operators to take full advantage of these benefits.

The MXL85110 provides a complete processing chain from the various interface technologies of user’s data to analog baseband signals. Its main features include:

  • Glueless connectivity to the RF/IF analog circuitry via integrated AFE DACs and ADCs
  • Synchronous Ethernet (SyncE)
  • 1588v2, transparent clock (TC) mode
  • Full-duplex, single carrier, FDD modem
  • XPIC
  • Bit rates up to 10Gbps
  • Modulation from BPSK to 1024 QAM
  • Channels spacing of 50MHz to 2GHz
  • Baud rate up to 1600 Mbaud
  • Configurable LDPC or RS FEC channel codes
  • High phase noise immunity
  • Ethernet and GPI interfaces
  • In-band management link

The MxL85110 is available from MaxLinear’s worldwide sales team and is also being showcased for early 5G field trials during the on-going Mobile World Congress 2017.
