LONDON Lime Microsystems Ltd. (Guildford, England), a developer of multiband multistandard RF transceiver ICs, has announced that it is collaborating with Percello Ltd. (Ra'anana, Isreal) to develop a reference platform for femtocell designs.
The reference platform combines Percello's PRC6xxx baseband IC, with Lime's LMS6002 transceiver IC. It will be used to develop femtocell designs for UMTS/HSPA+ air interfaces.
HSPA+ calls for throughputs of 21.6-Mbps down and 5.76Mbps up. The reference design supports extended cell range for enterprise and outdoor applications with the capability to cascade two or more PRC6xxx to support 32 and 64 simultaneous users.
Lime Microsystems' LMS6002 is a frequency agile transceiver that operates at user-selectable frequencies between 375-MHz and 4-GHz and is suitable for 3G, WiMax and LTE standards. The transceiver can be digitally configured to operate in the full range of frequency bands, with 16 user-selectable bandwidths up to 28-MHz. This removes the need for individual transceiver chips for each of the different bands.
"Percello's cost- and performance-optimised baseband solution is an excellent match for the capabilities of Lime's transceiver for high data rate solutions," said Ebrahim Bushehri, CEO of Lime Microsystems, in a statement.
"Lime's IC integrated with our technology quickly and successfully. We've addressed all interface requirements between the baseband and transceiver ICs, and the technology is now ready for easy adoption by our end customers," said Shlomo Gadot, CEO at Percello.
