1 Michael Crowley FARRAN TECHNOLOGY The Search for Bandwidth 60GHz Communications Interlligent 2015 RF & Microwave Design Seminar Cambridge 2015

2 Introduction Farran Technology mmwave Technology Applications Backhaul WiFi Test Solutions Summary Presentation Overview

3 1978 : Farran Technology Limited (FTL) established by faculty staff from University College Cork, Ireland - 35 years experience in millimeter-wave industry, specializing in products at operating frequencies from 30 GHz to 3 THz : Acquired by Smiths Detection (part of Smiths Group : 4b annual turnover) Security screening ( TADAR ) spun out as separate entity. FTL transferred to Smiths Interconnect 2013 : MBO initiated in Farran and completed in October 2013 now 100% owned and operated by Farran Management Team

4 FARRAN FACTOIDS: Over 100 years combined mm-wave experience in mmwave Design and Production >22 years combined mmwave design experience >48 years combined mmwave production/test experience >31 years combined mmwave CAD experience Design/Production/Test capabilities from 30 GHz to 3 THz

5 mmwave Developments In the past three decades there has been extensive research & academic development in the area of mmwave technology Corresponding growth in customer demand for components and systems Large number of test solutions available Signal Generators Spectrum Analysers Network Analysers Etc V-Band & E-Band increased popularity for communications/broadband

6 Backhaul LAN mmwave Broadband Applications Predicting that by 2020 high capacity base stations will typically require backhaul in the 1Gbps range Mobile broadband LTE (4G) & LTE Advanced (5G) will be more widely deployed towards 2020 Mobile Broadband networks will need to evolve to satisfy increasing capacity needs WiGig Ericsson, Alcatel/Lucent, Huawei, Qualcomm, etc Promoting the adoption of multi-gigabit speed wireless communications operating over the unlicensed 60GHz frequency band Apple, Broadcom, Huawei, Intel, Qualcomm, Sony, Samsung, etc

7 Backhaul Overview Total spectrum available for backhaul covers ~ 40GHz Range Amount of Spectrum Hop Length Channel Spacing Area 6-13 GHz 5 GHz XL S - M Rural GHz 5 GHz L M Suburban GHz 13 GHz M M - L Urban 60 GHz 9 GHz XS XL Urban 70/80 GHz 10 GHz S XXL Urban 6 13GHz Low frequencies long range will continue to be popular and grow, capacity limitations due to typically narrow channels 15 23GHz are the most widely used bands globally, and will continue to be 26 42GHz Currently 38GHz is utilized in Europe, wider channels will allow for gigabit capacity difficult for the two lower bands

8 Backhaul Overview V-Band (60GHz) Ideal for small cell backhaul, high capacity & high repeatability High capacity from the wide channels High repeatability due to the interference reduction from the oxygen attenuation E-Band (70/80GHz) new and fast growing Wide spectrum and channels more capacity Band use being encouraged by light licensing & low spectrum fees

9 WiGig LAN Overview In laymen's terms microwave Wi-Fi Aimed at superfast upload/download for someone near the router Support multiple-gigabit data rates Known as ad WHY??? Game machines Video cameras - streaming 4K televisions

10 RF Frequencies LAN Overview WiGig ad Spectrum Emission Masks - Frequency channels 55.26GHz 58.32GHz 60.48GHz 62.64GHz 64.80GHz 67.86GHz Channel Centre [GHz] Min [GHz] Max [GHz] BW [GHz]

11 Communication Link Frequency Extenders S-Parameter characterization at RF & microwave frequencies is readily available in most VNA s on the market today, high frequency VNA s or through frequency extension solutions Farran supplies these solutions Increased interest in 60GHz communication links Increased interest in how best to characterise & test these links FCE-15 system Designed to work with Arbitrary Waveform Generators (AWG) driving the upconverter chain with external signal generator controlling the LO frequency Low noise receiver on the downconverter side with suitable oscilloscope

12 FCE-15 Upconverter Architecture Challenges - Upconverter Operating bandwidth Transmitter P1dB/Linearity Spectrum purity In band flatness Architecture Dual Up-conversion Custom designed PA Numerous Filters Isolators & careful S-Parameter matching

13 FCE-15 Downconverter Architecture Challenges Down-converter Operating bandwidth Receiver Sensitivity Spectrum purity In band flatness Architecture Broadband components not as much as issue as up-converter High spec LNA Filtering Isolators & careful S-Para matching

14 FCE-15 System Reference Golden Transceivers Individual up/down converters for transmitter or receiver testing Combination of up and downconverter Antennas Components Subsystems

15 FCE-15 System
