Circuits lab logo - link to circuitslab.calit2.netCalit2's Circuits Lab specializes in the design, assembly and testing of new wireless devices, techniques and systems. Such a facility is rarely, if ever, found within a university environment. Comprised of Calit2's dedicated electrical and mechanical engineering staff, the group brings extensive expertise in RF, wireless, power, networks, sensors and circuits to its collaborations. The group also trains undergraduate and graduate students and participates in student projects for didactic courses.

There are 7 major environments in the Circuits Lab:

  • A mm-Wave lab, focusing on frequencies of 20mHz - 110GHz, and including u-Probe stations, a low-noise shield room, plus miscellaneous equipment such as micro-amps and micro-meters.
  • A power lab, specifically, 200mW - 2000W, with state-of-the-art amplifier test beds and a strength in battery management.
  • An assembly lab, in which various prototypes are produced and tested.
  • A Wet-Etch Lab, to build circuit boards, including plating and coating.
  • A wireless platforms lab, equipped with DSP & FPGA development tools, system integration and an interoperability test-bed
  • A base-station lab: a roof-top on-the-air cellular service under experimental licenses for research use.
  • An antenna-garden lab, consisting of a rapid-antenna-deployment test-bed with connections to various other labs.

Successful collaborations with UCSD and industry researchers have yielded notable outcomes including:

  • Novel ad-hoc mesh networks
  • Portable software-defined radios
  • Wireless medical response devices
  • MIMO devices
  • Personal mobile pollution sensors
  • Wireless health monitors
  • The world's record for power-efficient cellular & WLAN power amplifiers (useful in base-stations and long-battery-life cell phones, among others)
  • Micro-power generators and efficient battery energy extraction and charging
  • 1uA, 1.8V always-on wireless triggered receiver, having 1/f noise reduction with switched transistors (the lowest power, lowest noise no-delay radios)
  • Adaptive digital pre-distortion and memory effect inversion algorithms, for efficient linear amplifiers
  • Mobile emergency wireless networks for restoration of city-wide communication during a crisis
  • Mobile mini-mesh network nodes on the ground and in the air, with multiple gateways
  • "Always-Best-Located" and "Always-Best-Connected" communication systems
  • Ubiquitous communications that "learn" your habits

The Circuit Lab is a resource that is available to everyone, for design, prototyping, testing and deployment of electronic devices. Cost-sharing includes a recharge for use of a subset of equipment and a percentage of engineering staff, as appropriate.
