Workshop Background:

This is the IWPC’s 7th Base Station Power Amplifier Device and Sub-System Workshop. These workshops have explored the state of RF Power Amplifier technology and addressed the important topics that need to be discussed within the different levels Supply Chain.


Workshop Goals:

The Goal of this workshop is to gather all members of the supply chain that represent the RF Power Amplifiers – R&D, semiconductor device design, circuit implementation, BTS OEMS for Macro, Micro, Pico and Femto Cells, operators, installation and maintenance.

1) To understand the state of the art of PA technology.
2) To clearly identify what can be done to reduce Operator OPEX & CAPEX.

PA Technology Requirements for Ground and Tower-based Macro Cellular Base Stations and Small Cells (Micro/Pico)


  • Which PA Amplifier Technologies are better suited to which modes (wave forms or modulations)?

    • GaN on Silicon

    • GaN on Silicon Carbide

    • GaN on Diamond

    • GaAs High Voltage HBT

    • LDMOS

    • Other


    • 3G

    • LTE

    • WiMAX

  • Tradeoffs of Tower Mounted vs Ground Mounted PA Requirements?

    • power output requirements

    • bandwidth requirements

    • cooling requirements

    • operating temperature

    • linearization requirements

    • efficiency requirements

    • costs


RAN Sharing/Tower Sharing (i.e. – Multi-Standard Radios)-

  • How will Multi-standard/Multi-mode Radios affect PA requirements?

  • How can the wide RF BW needed (>100 MHz) be achieved with the same performance as Narrow-band PAs?

  • How do demands for reduced SKUs (ship the same PA for different frequency bands) affect the PA requirements?

SON Controls (Self Organizing, Self Optimizing Networks) -

  • How can the PA be controlled to allow Power Consumption optimization? (Time of Day or Traffic-Load-Dependant controls)

  • What are the implications of applying Controls to the PA?


CAPEX and OPEX Cost Implications -

  • There are New Techniques, New Ideas/Topologies, New Devices – what is the CAPEX advantage/disadvantage when implementing them?

  • Can the New Techniques, New ideas/Topologies, New Devices save OPEX? (Power Consumption, Heat, Size, Reliability)

  • Is there is an optimization possible for 'Nominal' Average Power, as opposed to the Peak value?

  • How many dB below the Peak Power is where the majority of the PA lifetime will be spent?

  • If a BTS is sized for the “mature” power level, is there is a chance for CAPEX reduction?

  • What are the costs to design the thermal management to the Peak Power vs. the Average Power level?

PA Device, Efficiency and Linearization Technologies
Status and Innovations


Efficiency -

  • A Review of the Power Efficiency of the different technology/topology options – with an Efficiency roadmap.

  • Do the efficiency improvements apply only to Macro Cell PAs, or do they apply to Micro/Pico PAs also?

  • How does Envelope Tracking combined with HBT technology compare to Doherty implementation?

    • Which has the better long-term potential to achieve the best overall results?

Linearization -

  • What is the effectiveness of different Linearization Techniques for different output power, bandwidth and waveform applications?

  • What are the ‘Gotchas’ on Linearization for the different technologies (Doherty vs. Envelope Tracking vs. SMPA implementations)

  • Aside from device specifics, how do the different devices Linearize when exposed to the different technologies like Envelope Tracking, Doherty, etc.?

  • How to pair DPD with the correct circuit topology to get the most efficient design?

  • Where are we with Analog Linearization schemes?

  • What are the Advantages and Disadvantages of Analog Linearization compared to DPD?

  • Efficiency is now a ‘granted” parameter – so how much Instantaneous bandwidth can be achieved? (Is the old 20 MHz standard changing to 30 or 50 MHz or more Instantaneous bandwidth?)

  • What about the linearity of the other sections around the PA device?

  • What about designing to “Typical performance” specifications compared to “Worst Case Performance” specifications?

  • What about Standardized Testing Conditions for devices?
