Wireless applications remain the dominant segment of GaAs
device market, accounting for just slightly less than 80 percent of all revenue.
Asif Anwar, Director in the Strategy Analytics Strategic Technologies Practice (STP) added, "The chief use of GaAs
MBE wafers has been for HEMT devices in handset switching applications but device manufacturers have been moving away from GaAs
for these switches.
Codification of Statements on Auditing Standards provides GAAS
standards applicable to audits of nonissuers and identifies differences between GAAS
and PCAOB standards.
GaN shows great promise for application in amplifiers that support higher frequencies than the microwave band, since it offers higher saturation electron velocity, higher dielectric breakdown voltage and a higher operating temperature range than GaAs
2) The hypothesized improvement in the crystal structure of space-grown wafers is irrelevant, since the GaAs
chip manufacturing destroys and rebuilds the crystal as part of the process.
Asif Anwar, Director in the Strategy Analytics Strategic Technologies Practice (STP) added, "We remain convinced that data consumption and GaAs
content in handsets will increase, but fluctuations in the global economy will put a damper on network and consumer spending.
Some of the key findings from the report, GaAs
Industry Outlook 2013-2018, as related to GaAs
demand from the defense sector include:
If a private-company client says it wants you to use "some" PCAOB auditing and related professional practice standards instead of GAAS
or in addition to them, you need to know what the client is trying to achieve.
The wireless communications segment continues to be the largest user of GaAs
The auditor's responsibility in a GAAS
audit for consideration of the internal control structure and compliance with laws and regulations, the additional responsibilities under the yellow book and the added testing of internal controls and compliance required by the Single Audit Act and Circular A-128 must be communicated to the auditee orally or in writing.
The Strategy Analytics forecast segments the SI GaAs
bulk substrate market by diameter, geography, growth method, application and supplier.
Between 70 to 80% of Skyworks' and RF Micro Device's GaAs
business is in PAs.
