- Devices Compliant to Tier-one, Carrier-driven Specifications
Mass., May 13, 2013 – Skyworks Solutions, Inc. (NASDAQ: SWKS), an innovator of high performance
analog semiconductors enabling a broad range of end markets, introduced groundbreaking RF switching
technology that is enabling early adopters to implement carrier aggregation solutions.
Carrier aggregation allows mobile service providers to combine spectrum and increase data rate
throughput by utilizing two or more bands simultaneously instead of the single band method used
currently, thereby giving consumers an enriched data experience regardless of location.
Skyworks' devices support standardized inputs to popular industry chipsets (MIPI RFFE compatible)
and address both transmit (Tx) and receive (Rx) switching paths.
"Skyworks' carrier aggregation
switching solutions, which are compliant to tier-one, carrier-driven specifications, offer dedicated
receive diversity functionality to accompany the primary antenna-switch path," said David Stasey,
vice president and general manager of analog solutions at Skyworks. "These devices demonstrate
that Skyworks is once again at the forefront of technology innovation – leveraging our technical
breadth, depth and commitment to delivering best-in-class solutions."
are driving carrier aggregation to help increase the efficiency and speed of today's saturated
mobile networks, particularly as consumers download an ever increasing amount of mobile content
via smartphones. With the limited availability in the wireless spectrum, carriers are
seeking innovative RF solutions as a means to fully utilize their allocated spectrum.
About Skyworks' Switch Technology
Skyworks offers a broad selection of RF
switching solutions based on silicon on insulator (SOI) and pseudomorphic high electron mobility
transistor (pHEMT) wafer process technologies, complementing its world-class, silicon and gallium-arsenide
power amplifiers and front-end solutions. Skyworks' switches are available in many different
configurations including ultra-high linearity, low insertion loss, high isolation, broadband,
reflective and non-reflective.
is a double-pole, 14-throw (SP7T/SP7T) antenna switch module for primary antenna transmit.
The switch features low insertion loss, high isolation, exhibits excellent IMD performance and
is designed to meet stringent requirements of B17 third harmonic. Switching is controlled
with an integrated mobile industry processor interface (MIPI) decoder allowing the low band
and high band sections to be independently controlled by two separate registers. No external
direct current (DC) blocking capacitors are required. The switch is manufactured in a
small, 2.8 x 3.2 millimeter (mm), 26-pin multi-chip module (MCM) package.
is a dual pole, 12T (SP7T/SP5T), MIPI-controlled antenna switch designed specifically for Rx
diversity in carrier aggregation applications. The SP5T switch is optimized for the low
band, while the SP7T is for high band. Using advanced switching technologies, the device
maintains low insertion loss and high isolation for all switching paths. The switch also
exhibits excellent IMD2/IMD3 performance. Packaged in a small 2.5 x 2.9 x 1.0 mm, 22 lead
MCM package, switching is controlled by a MIPI decoder and requires no DC blocking capacitors
on the RF paths.
