ZTE Ships Home-grown LTE Modem in USB Dongle

ABI Research reports that ZTE is shipping a home-grown LTE modem inside one of its own LTE USB dongles. The ZTE ZX297502 is a second-generation LTE modem from ZTE. Jim Mielke, VP of engineering at ABI Research, comments, “ZTE recently announced the WiseFone 7510 LTE modem for release early this year but the 7510 is a third generation LTE chip. The first generation was mainly a prototype; the second generation was the first real production chip and is certainly the basis for the 28nm 7510 scheduled to be released early 2014.” The ZX297502 is strictly a modem baseband; it is accompanied by ADI and ACP transceivers, and a TI power management unit (PMU).

A complete teardown of the ZTE LTE chipset and accompanying chips is available from ABI Research’s Teardown Service. The full teardown includes a complete bill of materials w/cost estimates, high resolution dismantling and board photos, and component die photos and X-rays.
