Possible LTE cat 4 modem chips
I’m curious and am playing around with a new EDA tool and am looking at practicing by designing a PCB which should be roughly 28x26mm footprint (give or take a few mm…).
It should be an LTE cat 4 device, connected by USB type C for the framework laptop and is unlikely to include antennas.
Where I struggle is identifying potential modems to use. The only one even remotely close is the u-blox LARA-L6, which is 24x26mm. What alternatives are there?
I am trying to see what gets sold in these USB dongles but there is little info. The few I have identified seem to make use of the Qualcomm 9207, but its’s unclear to me if its a ready chip (which is what the MDM9207 is?) Or if it is an IP core to integrate in one’s own chip?
A video I came across seem to indicate it (the MDM version) is tiny:

But will probably needadditional things to be integrated and I created an account at Qualcomm but they won’t give anything unless I’m certified from a company to be a customer and actually integrate it…
