25 + Years in Silicon Wireless Ran Yan
UCSB: 1986 - 1990 • Have a GREAT Team • Be Persistent 2
Silicon Wireless: Device Wireless + Low-Power = Mobile Internet !
Silicon Wireless: Circuit Wireless LAN (WiFi) worldwide sales: • < 0.1 M units in 1997 ➢ A card cost ~$130 to make • An opportunity to grow to > 2 M units ➢ Apple’s iBook & AirPort in 1999 ➢ Steve Jobs offered $50 to buy ➢ Productized a 0.35- m m Silicon RFIC (radio frequency integrated circuit) in ~18 months to reduce overall cost by > 5x
Silicon Wireless: Single-Chip Technical Significance: • Single Chip (Digital+RF) • Support Multiple-Antenna (2x) • 1 Gbps Data Rate RX BB ADC RX RF 1.2 mm Synthesizer DAC TX RF 1.2mm Digital Signal Processor
Silicon Wireless: SOC (System-on-Chip) Radio Frequency & Significance: Analog Circuit • Commercial value • RF/Hardware complexity removed • Wireless product engineering Digital Signal Processor becomes software projects • Enables: ➢ Internet of Things ➢ Wearable sensors Micro-Processor Core Multi-Port Memory USB 6 mm (For Illustration Purpose Only)
