FlexDPD is a comprehensive adaptive digital predistortion solution that is scalable and independent of the target device vendor hence it can be built for any FPGA/SoC or ASIC platform.
Advantages include:
- Vendor independent: compiled for your preferred FPGA or silicon vendor.
- Scalable: resource optimisation for bandwidth, performance and multiple antennae/MIMO.
- Affordable: licensing terms to suit your business and roadmap.
- Accessible: evaluation on your own hardware or using an off-the-shelf platform, contact us for details.
- Supported: your success with FlexDPD is our core business.
Supplied with:
- Comprehensive documentation.
- Integration and performance analysis tools.
- Support from highly experienced radio systems engineers.
Technically advanced, FlexDPD linearization technology includes the following benefits:
- Maximises efficiency by enabling amplifier operation in the non-linear region. Greater than 50% efficiency can be achieved when coupled with the latest GaN devices in a Doherty configuration.
- Amplifier distortion improvements of > 45 dB have been attained.
- Enables multi-carrier and multi-standard single-antenna transmissions.
- Adaptive compensation for power amplifier memory effect.
- Adaptive compensation for both Tx and observation path AQM impairments.
- Operation with Tx occupied bandwidths over 1 GHz, only limited by the target hardware capabilities.
- Agnostic to transistor technology (e.g. LDMOS, GaAs, GaN) and amplifier topology (e.g. class A/B, Doherty).
- Agnostic to the communications standard: works with multi-carrier, multi-standard FDD, TDD, 2/3/4/5G, DVB-T, DVB-S2X, BGAN and many others.
- Low target resource footprint, which is also scalable to suit the requirements.
- Compatible with technologies such as Crest Factor Reduction (CFR) and envelope tracking.
- Inherently compatible with 7-2x O-RAN deployments (O-RU).
