will your product have? Any wireless
design requires careful placement
of the RF circuit within the system.
60GHz adds additional challenges due
to the properties of short millimeter
waves. In small form factors such
as smartphones, heat dissipation
and thermal management will add
complexity as well.
Budget. Depending on throughput,
distance, form factor, and placement,
different wireless components and
system level implementation will
impact the final cost.
Conclusion
With the 2.4GHz and 5GHz ISM bands
approaching capacity saturation, the
unlicensed portion of the millimeter-
wave band offers a much-needed
piece of open spectrum where wireless
devices can enjoy new dimensions in
capacity and access. Standards are
already in place to define both indoor
Wi-Fi service and outdoor long-haul
links for point-to-point links as well as
"last block" mobile access. Millimeter-
wave technologies also show promise
for use as ultra-short-range "wireless
connectors" which eliminate the
durability, EMI and industrial design
issues associated with traditional
mechanical connectors.
Advanced CMOS technologies are
making it possible to unlock the
potential of all these applications
of the unlicensed 60GHz frequency
spectrum in an economical manner.
SiBEAM is one of the few companies
in the world that has mass-produced
millimeter-wave ICs in high-volume
CMOS fabs on multiple process
nodes for over a decade. Part of the
company’s success can be attributed
to its proven closed-loop design
for production process where the
device's production test vectors are
created using inputs from collected
data from the CMOS processes used.
During production tests, the results
produced by these highly-accurate
test vectors are then used as feedback
by designers to fine-tune the design
for optimal yield and performance.
The methodology can be migrated
between process nodes at different
manufacturing foundries. SiBEAM
provides support through every phase
of design, manufacturing, test and
deployment including: RF design,
thermal management planning;
ackaging
and
implementation;
compliance testing, FCC Part 15B and
Part 15C.
