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
