500 MHz 3dB bandwidth quadrature modulator
ICs for cellular infrastructure
Skyworks Solutions, Inc. has introduced three wideband
quadrature modulators for cellular infrastructure and high
performance radio link applications. Skyworks' modulators
are the latest additions to its wireless infrastructure
portfolio and designed to support the world's leading 3G
and 4G base station providers.
Skyworks says these new, fixed gain quadrature modulators
deliver excellent phase accuracy and amplitude balance enabling
high performance for a variety of multi-carrier communication
systems. These new modulators have greater than 500 megahertz
(MHz) 3dB modulation bandwidth, a low noise floor, and a
wide operating frequency range that support multiband designs
and network requirements, adds Skyworks
According to a recent In-Stat Mobile Internet Group research
report, infrastructure expenditures by mobile operators
will need to scale up by more than 40 percent in the coming
years to meet fast approaching network demand. As a result,
mobile operators will not only need to install new base
stations, routers and backhaul network equipment, but will
need to upgrade and expand existing infrastructure to avoid
network traffic jams and preserve their highly profitable
data service revenue, all of which will require increased
analog and mixed signal content.
"With the addition of these new modulators, Skyworks
continues to capitalize on the network infrastructure side
of the mobile Internet phenomenon," said Liam K. Griffin,
Skyworks' executive vice president and general manager of
high performance analog. "Skyworks is pleased to offer
our customers a multitude of high performance, cost effective
solutions as they build out their networks to support the
staggering increase in mobile data traffic."
