Radio Hardware Platform

• How many ASICs?
• Single-chip radios or separate RF BB ASICs
• External RF components antennas, filters, PAs,
  switches,
• How many modules?
• Antennas distributed all over the product
• Increased ASIC integration level not any more the
  only driver in system architectural partitioning
• Options
• Separate single-chip ASICs or system modules
  close to antenna
• One centralized modem with distributed antennas
• Something in between (including different
  choices)

A Fully Integrated SoC for GSM/GPRS in 0.13µm

• Crosstalk from the digital blocks into RF is one
  of the biggest concerns in single-chip
  transceivers.
• Substrate noise pickup, package crosstalk,
  magnetic coupling between the coils, and supply
  coupling degrade the RF performance.

Cell-Phones

• Cellular phones with embedded GPS engines will
  enable network-based positioning methods.
• Assisted GPS solutions allow a direct migration
  path into 3G handsets besides being more accurate
  than cell tower-based ones.

DVB-H

• DVB-H is a new standard that is expected to be
  widely deployed in future mobile devices.
• The first DVB-H field trials were held in Europe
  and used the UHF band.
• DVB-H has also been targeted for deployment in
  the United States using L-band spectrum between
  1670MHz and 1675MHz.
• There has also been discussion of reallocating
  European L-band DAB frequencies for DVB-H service.

Software-Defined Radio Receiver

• A software-defined radio (SDR) can tune to any
  frequency band, select any reasonable channel
  bandwidth, and detect any known modulation.
• While progress has been made on DSP and baseband
  functions for SDR, the low-power radio front-end
  has remained elusive.
• An ADC at the antenna which digitizes all bands
  simultaneously with equal fidelity will not be
  practical in the foreseeable future.
• Todays mobile SDR receiver needs a wideband,
  linear RF front-end that can be tuned to any one
  channel at a time in the band from 800MHz to5GHz.

• The on-chip receiver selectivity at 900MHz is
  sufficient for GSM and at 2.4GHz for 802.11g WLAN

Conclusion

• Multi-Standard Radio Design is not only an ASIC
  level issue
• Hierarchical design and design abstraction are
  needed in system design
• Hybrid solutions cover numerous different options
  to realize Multi-Standard Radio
