PROJECT BACKGROUND
indie is the operator-independent hardware platform that enables global LTE
smartphones. Co-designed and optimized by EPCOS, a TDK group company,
and Pulse Electronics, indie builds on advanced EPCOS multi-feed RF front-end
technology and cutting-edge antenna technology from Pulse Electronics. indie
provides the single RF platform sought by the Next Generation Mobile Network
(NGMN) operator alliance.
THE DESIGN CHALLENGE
The design challenge was to create an operator-independent RF hardware
platform that enables global roaming and downlink inter-band carrier
aggregation for future LTE mobile devices.
THE SOLUTION
The solution relied upon AWR’s software, specifi cally Microwave Offi ce, for the
design of a 3-feed antenna system and RF front-end module architecture. The
software enabled exploration and resulted in the elimination of the need for the
region-specifi c duplexer matching (necessary in single-feed architectures) such
that universal operator-independent applicability resulted. Moreover, the 3-feed
architecture improves the system performance by up to 2 dB, and facilitates
WLAN interoperability given better intermodulation linearity.
Additionally, Pulse used AWR software to create circuit simulations of the
antenna system and the matching circuits, as well as a general documentation
platform. EPCOS used Microwave Offi ce for the circuit simulations of the
front-end module including couplers, switches, duplexers, fi lters and diplexers,
as well as for the modeling of the nonlinear passive duplexer.
