1 TUNABILITY in Wireless Mobile Applications March, 2009
2 About Paratek Founded 1998; Privately funded Adaptive RF Tuning Solutions For all wireless applications Enables ultra-small & thin tunable antennas that adapt to human variances and mechanical use cases Tunable material: ParaScan Building blocks: Passive Tunable ICs ( PTICs ) & HVDAC Controller ASICS Products: AIMM & RAFT Fabless model Partner with select fabs to manufacture PTICs 2
3 TUNABILITY Value Propositions Faster Data Rates Reduced Power Consumption Thinner More Stylish Phones Less Dropped or Missed Calls Faster Time To Market Greater Cell Site Area Coverage Consumer Electronics Manufacturers, Service Providers, and End-Customers ALL benefit 3
4 Tremendous Opportunity in the World s Largest Electronics Market Thin, more stylish iconic and smart phones are great but easily detune due to ever-changing use cases such as slider position, user grip, phone in pocket, Paratek s revolutionary closed loop tuner, AIMM, dynamically retunes the phone s radio to maximize power reaching the basestation Significant benefits to end user: Longer battery life / talk time Less dropped calls Faster data rates Efficiency y( (call quality) Frequency (channel) 4
5 Significant Value for ANY Mobile Wireless Device 50% increase in battery life More rapid product development for up to 3 months faster time to market Km increase in 3G cell radius 67% improvement in dropped call rate 40% thinner antennas for thin iconic phones 2-4x improvement in data rate 5
6 All Major OEMs are Modifying Select Next-Gen Platforms to Insert Paratek Adaptive RF Tuners 6
7 The Engine Behind Paratek s Products Paratek uses a combination of additives to BST to create a superior dielectric material (ParaScan ) having Lower Leakage, Higher Q, Better reliability ParaScan material is used to create tunable capacitors (PTICs) which change their capacitance based on applied voltage Highly reliable, production-ready process 7
8 PARATEK / ST Partnership Recognized Tunable Technology Leader Strong IP Portfolio and Systems Expertise One of 5 Top Semiconductor Suppliers; $14B in Revenue Significant Market Share in Mobile Phone Applications Accelerating Market Adoption Partnership will leverage ST experience to manufacture PTIC wafers in high volume 1 st generation PTIC wafers available today; 2 nd generation product available from ST FAB at the end of 2009 ST s extensive silicon capabilities will further enhance Paratek s silicon ICs needed in AIMM and RAFT RF modules will be jointly designed and industrialized 8
9 Open or Closed loop Antenna Tuners Radio Antenna Frequency Tuner: HVDAC PTIC Maximizes power delivered between the antenna and the radio in known conditions such as frequency band, mechanical position (sliders/flip open/closed) Controlled via commands from the baseband. Algorithms (to sense and adjust for detuned conditions) residing in either HVDAC PTIC Standalone CP CP in ASIC Baseband DSP Adaptive Impedance Matching Module: Same as RAFT but works autonomously with integrated sensors that sense any mismatch conditions in each band of use and all mechanical & loading conditions. 9
10 Implementation of Antenna Tuner Module RAFT Antenna AIMM Antenna SMD PTIC CPL SMD PTIC CNTL IC 32bits SPI ADC ADC LOG AMP LOG AMP CNTL IC 32bits SPI Radio Antenna Frequency Tuner (RAFT) Open Loop LGA Package 4x4mm Digital command required to direct RAFT to each tuning state Adaptative Impedance Matching module (AIMM) Closed loop include coupler and detector LGA Package 5x6mm Fully adaptive, best performance for all conditions including band / mode / head detuning / mechanical position. Tuning algorithm integration into baseband Both solutions replace the fixed match at the feedpoint of the antenna 10
11 Measured Total Radiated Power Improvement vs. Frequency Channels Antenna Tuner 3 PTiC design From 2dB to 10dB improvement Samsung SGH-L700 Eureka TRP Data CTIA Approved Facility Now SGH-L All (Baseline) Bands Vs SGH-L TRP > (RAFT 20dB V4) RP (dbm) T Digital Control IC Channel No. Baseline (dbm) RAFT 14 V4 (dbm) 11
12 Total Radiated Power Improvement vs. Antenna Volume Measured Phone Models W270 (clam) P310 (credit card phone) Sprint Lab (slider) Z720 (slider) ANT Volume (physical) 0.51 cc (51 x 5 x 2 mm) 1.15 cc (46 x 5 x 5 mm) 2.90 cc (43 x 10 x 6.75 mm) 4.23 cc (47 x 10 x 9 mm) TRP Improvement with Tunability 2.5 ~ 7 db 2 ~ 4 db 1 ~ 1.5 db 0 ~ 2 db Improvements from tuning increase for ultra-low-volume low antennas with multi-band requirements 12

14 Conclusion Benefits of Tunability in Mobile application OPEN LOOP Tuner control based on open loop parameters, according to a table identifying predefined known states Baseband Static Tuner Control PA TRX FEM SPI RF tuner CNTL IC Faster Data Rates ~2x ~4x Higher signal strengh and lower distortion Larger cell sites (3 to 6dB link improvement) Infrastructure savings (less base station) Enable Thin handsets ~40% antenna size reduction Small Antenna = Small Bandwidth with adaptive tuning. CLOSED LOOP PA Improved Talk Time Improved antenna match & radiated efficiency -30% reduction in Battery power consumption Fewer Dropped or Missed calls Tuner control based on forward & reflected power measurements, requiring a dedicated algorithm to optimize i the RF tuner settings Baseband Dynamic Tuner Control TRX FEM Sense SPI RF tuner CNTL IC Eliminate Body effects that de-tune Antenna Evolutionary improvement with mode & band tuning (RAFT) Revolutionary improvement with self-adaptive tuning under any condition (AIMM) Accelerate TTM : Less Antenna tweaking Works with all RF Standard (GSM, CDMA, WCDMA ) and WiFi and WiMax 14
