JPMorgan reports Broadcom (BRCM +1.6%) will ramp shipments of 4G baseband chips to Samsung in Q1 for use in mass-market phones, and has also scored 4G baseband wins with another top smartphone vendor.
Any 4G share gains by Broadcom would likely come at Qualcomm's (QCOM +0.1%) expense. Qualcomm had a 97% 4G baseband share earlier this year (per Strategy Analytics), and just announced a new baseband modem that leverages TSMC's next-gen 20nm manufacturing process.
Investors have already expected Qualcomm's 4G baseband share to fall some in 2014, thanks to fresh competition from Broadcom, Intel, and Nvidia.
The JPMorgan report is a breath of fresh air for Broadcom investors, given the company's disappointing Q4 guidance was partly due to baseband weakness.
