Yeah, there are only a small handful of companies making radios for mobile networks that I am aware of - its really hard. Qualcomm, Samsung, Mediatek, Apple?
There is also HiSilicon (Huawei), Unisoc (formerly Spreadtrum) also exists in the ultra-low-end segment formerly occupied by Mediatek, and then a bunch of miscellaneous ones like Leadcore, Nufront, and Rockchip.
