RF Signal Generator for 5G applications

APPLICATIONS

Innovative TX Signal Generation Solution that convert a digital signal to an analog waveform compliant to 3GPP Standards.

This disruptive system promising performances as for the realization of a 5G handset transmitter with moderate hardware complexity and low power consumption.

Architecture intended to address future wireless transmission requirements :

• LTE-A,
• Sub-6 Ghz 5G,
• Internet Of Things.

DESCRIPTION

The signal generation is based on a piecewise linear approximation, resulting from the use of a differential digital coding associated with a custom digital-to-analog converter (DAC), named here the Riemann Pump. The intrinsic performances of this architecture in terms of quantization noise make the Riemann Pump an efficient DAC for multi-carrier applications.

BENEFITS

• Energy efficient data conversion,
• High flexibility radio design and bandwith 3GPP standards compliance,
• Carrier aggregation intrinsic compatibility,
• Low footprint,
• Lab proof-tested solution with fab tapped chips.
