  1. Wireless Infrastructure(NXP’s) Industrial Perspective Domine Leenaerts BU Industrial & Infrastructure, RF ADT

  2. WirelessInfrastructure – NXP’s scope Point-to-pointcommunication 11 – 42GHz & 60 – 90 GHz Cellularcommunication 700-3000MHz

  3. Cellularcommunication – NXP’s scope • Largesignal IP • Everythingbeyond 10W • RF Power amplifiers • SmallSignal IP • Transmitter, receiver, • LO synthesizer • Excl. Data converters

  4. Cellularcommunication – NXP’s scope RFPower QuBic Technology RFss

  5. SmallSignal – the future (as we seeit) • GaAs willcompletelybereplacedbySiliconforreasons of • Yield, more functionality, … • Cost • Power dissipation • But, nocompremiseon performance!!! • Note: no performance differentiationbetweensmallcells and macro cells in smallsignal IP • Note: Automotive-likequalification!

  6. SmallSignal – LNA example At 65 degrees Celsius! Improvedlinearityrequired, cooperationTU Delft, L. de Vreede

  7. SmallSignalIntegration – the future (as we seeit) QuBic Technology

  8. + SmallSignal – Integration step OCP1dB=+24dBm OIP3=+42dBm G = 37dB Frac-N PLL 400 – 3000MHz Spurs < -70dBc Broadband match DSA VCA MPA 60dB attenuation range 12bit DAC 6bit SPI 3V3 Isolation? LO

  9. LargeSignal – the future (as we seeit) • Technology • Move from LDMOS towardsGaN Single device PA

  10. LargeSignal – the future (as we seeit) • Technology • Move from LDMOS towardsGaN

  11. LargeSignal – the future (as we seeit) • Technology • Move from 2-Way to 3-Way Doherty and GaN Higher PAE for 4C-WCDMA than LDMOS Basedon the 3-Way Doherty work in TU Delft

  12. LargeSignal – the future (as we seeit) • Architecture: from Doherty to out-phasing • Highlydigitized TX basedonout-phasingclass-E RF PAs • Allowreconfigurable (static) • Improvedsignalbandwidth • DE > 85%, PAE > 65% • Smallcells: 10 – 50W (peak)

  13. Large Signal – today’sSMPA TX line-up

  14. Large Signal – the nearfuture TX line-up “Digital” RF drivers, cooperationTU Delft, B. Staszweski

  15. LargeSignal – the future (as we seeit) PA Package integration TU Delft Supported

  16. Point-to-Pointcommunication • Microwavebackhaul is keyfor high performance mobile networks! Macro Point-to-Point Microwave -Backhaul Micro/Pico DL UL Backhaul

  17. Point-to-Pointcomm. - the future • GaAs IP will be replaced by Silicon-based IP • Cost, yield, power dissipation • Again: no performance degradation due to replacements • Phased Array Techniques • Ease of LoS connection • Focal plane concepts

  18. Point-to-Pointcomm. - the future • 29 – 31 & 33 - 36GHz • Up to 1024 QAM • 80 antennas, 5 indepentbeams

  19. Point-to-Pointcomm. – example VCO Can we do better? Spec point is -115dBc/Hz @ 100kHz!

  20. Concludingremarks • Move from III-V to Si technologyrequiresmassiveinnovation in technology, system/IC architecture and IC design • Move fromDoherty-based HPA towardsout-phasing SMPA digital TX requiresagainmassiveinnovation in technology, system/IC architecture and IC design As industry we cannot do thisalone, we needacademia to support us
