TriQuint Semiconductor’s motion sensing chip powers Delphi’s Automotive radar

TriQuint Semiconductor has made available its 77 GHz Gallium Arsenide (GaAs) chipset portfolio for motion detection and adaptive cruise control applications. TriQuint products are currently used by Delphi Automotive in its successful multimode electronically scanning radar (ESR) that enables adaptive cruise control in multiple vehicles. TriQuint 77 GHz chipset devices appeared first in 2010 model year automobiles.

The TriQuint 77 GHz portfolio includes eight products (TS-16949 factory certified) for use in motion sensing automotive and non-vehicular applications.

“At Delphi, we were looking for a chipset supplier with a track record of developing high performance products that would help us succeed in the commercial marketplace. TriQuint’s experience with GaAs modules and their ongoing support has helped us to provide our customers game changing driver assist technology,” remarked Mark Lynn, Chief Engineer, Active Safety, Delphi Automotive.

“We’re pleased to support a company like Delphi that has an industry-leading product line-up,” remarked Balut. “The microwave devices that Delphi has used in its ESR modules are now available for other motion sensing applications that require market-tested, automotive-qualified performance. The products are also cost-competitive for many different motion-based applications and concepts such as security systems.”

Technical Details – TriQuint’s 77 GHz Automotive-Qualified Chipset Solutions (TS-16949)TGA4705-FC
Flip-chip low noise amplifier with 23 dB small signal gain and a 5 dB noise figure at 77 GHz (typical) for Receive (Rx) chain architectures.

TGA4706-FC
Flip-chip medium power amplifier with 14 dBm saturated output power with 15 dB small signal gain at 77 GHz (typical).

TGS4305-FC
This 60-90 GHz SP3T switch offers a typical switching speed of < 5 nsec and when flipped provides a nominal 2.3 dB insertion loss, > 13 dB thru state return loss, and 20 dB isolation.

TGS4306-FC
This 70-90 GHz SP4T switch offers a typical switching speed of < 5 nsec and when flipped provides a nominal 3 dB insertion loss, 8 dB return loss in the thru state and 20 dB isolation

TGV2204-FC
A flip-chip voltage controlled oscillator (VCO) for frequency stability in Transmit (Tx) chains. It typically provides 7 dBm output power at 19 GHz with < -105 dBc/Hz phase noise at 1 MHz offset; its integrated divide-by-8 prescaler eases PLL design.

TGC4702-FC
