Silicon technology has made tremendous progress towards ever higher device cut-off frequencies. Nowadays all RF components for mm-Wave sensing applications up to 120 GHz can be realized.
Silicon Radar is a german company that designs and delivers Millimetre Wave Integrated Circuits (MMICs) on a technologically advanced level, manufactured in affordable Silicon-Germanium-Technology (SiGe). It has just introduced new development kits using GHz CMOS radar MMICs, which are built using SiGe or SiGe:C from IHP.

Silicon Radar participated in the European Commission 7th Framework Success project,  to develop ways to mass produce silicon mm-Wave SoCs at low cost – with STMicro, IHP, Evatronix, Selmic, Hightec, Bosch, the Karlsruhe Institute of Technology and the University of Toronto.

The development kits are:

assy_easyradarkit_270EasyRadar is for evaluating all of the firm’s TX/RX radar chips, and is “great for beginners and pros who want to start development and tweak system parameters”, said Silicon Radar.

EasyRadar features:

  • programmable FMCW parameters
  • signal processing
  • target recognition
  • web-based GUI
  • USB or wireless LAN communication with PC

The kit includes:

  • 122 GHz radar front end (see photo above)
  • 24 GHz radar front end (see lower photo)
  • controller board
  • baseband board with WiFi
  • lens for 122 GHz

simpleradar_270SimpleRadar is available to evaluate the firm’s 122 GHz radar front end.

It has the same functionality as the EasyRadar but is smaller (40 x 40mm), and can be used as a Wi-Fi-enabled radar sensor with integrated target recognition.

It has the following features:

  • programmable FMCW parameters
  • signal processing
  • target recognition
  • web-based GUI
  • USB communication with PC or over wireless LAN

“We offer high frequency circuits for radar solutions, phased-array-systems and wireless communications, for both custom specific ASIC design and supply of standard circuits in frequency range from 10GHz X-band up to 200GHz and above,” said the firm.

Possible applications using the kits are:

  • distance sensing applications such as industrial sensing (distance, speed, material characterisation),
  • public and private safety (motion detectors, even behind wall paper),
  • automotive (wheel suspension measurement, pedestrian safety),
  • replacement of cheap ultrasonic sensors (distance measurement)
