60 Ghz Ism Band

Overview

Over several years, TES has been investing significant effort in R&D, developing semiconductors and prototype systems for the 60 GHz ISM Band. Our customers benefit from an easy access to the developed IP and technology and our expertise in this area enables product development.

Consequently, using this advance, customers may be able to realize products or solutions with a competitive edge.

Why solutions in 60 GHz ?

The frequency bands 57-64 GHz, up to 66GHz in Europe are ISM bands and therefore open for license-free use. The following applications are a few examples of potential use cases:

  • Point to point links with > 1Gb/s throughput, e.g. for extension of GE networks
  • Back haul links for HSPA or LTE Radio Base Stations, license free, i.e. very cost efficient
  • Industrial / Medical sensor networks for the monitoring of vital signs, movement detection, etc., potentially replacing current costly 24 GHz systems
  • Femto cell data coverage with throughputs extending 1Gbit/s


TES’ recent semiconductor developments open a perspective towards low cost components in SiGe and CMOS Technologies.

The main benefit of using the 60 GHz ISM frequency band is obvious: license free use. The disadvantage is a very high attenuation of the air for radio waves in this frequency band. It is caused by the resonance of the oxygen molecules which results in high radio wave absorption. Depending on the application, this disadvantage may be partially compensated by the usage of directed high gain antennas which are physically very small. At the same time the high attenuation allows excellent frequency reuse and easy handling.

Why is TES an attractive 60 GHz design partner ?

TES has been continuously investing in 60 GHz technology for 7 years. TES has been participating in several European and German Research programs in this area. 60 GHz prototype silicon is available from

TES today, as well as several demonstrators with promising performance.
TES is an independent design service and technology provider, with application level expertise like e.g. 60 GHz communications and radar. Therefore TES is your reliable design partner for related 60 GHz system, sub-system and silicon design. The availability of prototype silicon as IP owned by TES enables customers to use TES’ advance to get to market faster and allows for feature differentiation.

TES is open for participation in all kind of 60 GHz pre-competitive, joined R&D public research projects.
