MaxLinear logoMaxLinear Inc. announced the MxL1100 family of fully integrated, all CMOS broadband microwave transceivers for 5G, wireless backhaul, wireless front-haul and satellite broadband applications. The first device, the MxL1105, is a broadband microwave transceiver that supports all licensed and unlicensed bands from 5 to 44 GHz, including all ETSI-defined channel spacing options from 5 to 224 MHz. It handles all QAM modulation code rates up to 4096 QAM.

The transceiver incorporates full receive, transmit, digital pre-distortion receiver feedback path and all synthesizer components on a single chip. The closed loop digital pre-distortion provides power amplifier (PA) linearization for a wide variety of PAs.

Full Spectrum Capture™ (FSC™) technology enables the MXL1105 to support a channel aggregation mode, enabling a second channel of any channel spacing to be processed within the same IC.

This single chip transceiver replaces custom, band-specific designs that require hundreds of discrete components, and it adds capabilities that can only be realized practically with an advanced CMOS process.

The MxL1105 is available now.

At Mobile World Congress 2017, MaxLinear will demonstrate the MxL1105 with a phased-array antenna, showing the flexibility of the platform to support multi-user MIMO and beam forming applications for the newly proposed 5G frequency bands.

Brendan Walsh, vice president of MaxLinear’s wireless infrastructure business, commented, “Commercially viable 5G deployments will require highly integrated MIMO transceivers with increased signal processing capabilities. The same single platform can be leveraged to drive 5G beam forming phased-array antennas for the main bands of interest from 28 GHz to 39 GHz and beyond. We are well positioned for this market and will show case our capabilities for early 5G field trials during MWC 2017.”
