Skyworks share price plummets over the last year
The company’s closing share price on 31st August 2012 was $30.46 and at the end of closing yesterday was $21.16
Skyworks Solutions Inc., a company that together with its subsidiaries, offers analogue and mixed signal semiconductors is currently down by 2.06 percent on 3,795,706 shares traded.
Tektronix’s DPO/DSA/MSO70000 Digital & Mixed Signal Oscilloscope using IBM’s 9HP SiGe technology
The next generation of performance oscilloscopes from Tektronix is due for availability in 2014. With real-time bandwidth of 70 GHz, and the potential for more in future iterations, the new oscilloscope platform will deliver the performance and signal fidelity needed for applications such as 400 Gbps and 1 Tbps optical communications and fourth generation serial data communications.
“By extending our long-standing relationship with technology leader IBM, Tektronix is continuing to push the envelope on what can be achieved in high-fidelity, high-speed data acquisition systems. Early adoption of 9HP has allowed our engineers to explore innovative architectures and performance thresholds once thought unattainable,” says Kevin Ilcisin, chief technology officer, Tektronix.
“The advanced 9HP SiGe BiCMOS technology provides the faster switching speeds, high integration levels, and low noise our next generation of performance instrumentation requires to meet customer requirements,” adds Ilcisin.
Improving Signal to Noise
In addition to leveraging the advances made possible by 9HP, Tektronix’ forthcoming oscilloscopes will benefit from the use of Asynchronous Time Interleaving technology to improve signal-to-noise ratio beyond the frequency interleaving approach in use by some vendors today.
In traditional frequency interleaving, each analogue-to- digital converter (ADC) in the signal acquisition system only sees part of the input spectrum. With Asynchronous Time Interleaving, all ADCs see the full spectrum with full signal path symmetry.
This offers the performance gains available from interleaved architectures but without the same impact to signal fidelity.
NASA to branch out into multiple compound semiconductors
Using MBE or MOCVD equipment, NASA Langley is seeking a facility for III-V semiconductor epilayer growth
NASA LaRC says it will fabricate and deliver a total of 60 wafers during 6 months.
Among these wafers, at least twenty wafers will be processed to fabricate multiples of working devices. The device fabrication will use silicon oxide/nitride deposit, photo-lithography with mask-aligner, wet and dry etching and thermal diffusion.
CONTRACTOR TASKS
The company says that it wants contractors to provide III-V compound semiconductors which include:
1. GaAs, InAs, AlAs July 2013

Skyworks is currently down by 32.6 percent from its 52- week high which has prompted Equity Profile Report to add the stock to their NASDAQ Decliners Watch List.
