LMS6002D support of LTE

Hi Srdjan, We're looking into re-purposing UmTRX for LTE and there a few things which we need to understand better. 1. Is it possible to support 15MHz and 20MHz LTE channel bandwidths? To achieve this we at least need to sample at 23.04Msps and 30.72Msps respectively. LMS6002D datasheet specifies the maximum I/Q samplerate of 14Msps, which is not enough. But at the same time, datasheet claims that ADC and DAC are specified up to 50Msps. How does this fits together? 2. Do you have any experience what maximum output power we could achieve with LMS and proper amplifiers, while still staying in the bounds of the LTE Standard? What would be the limiting factor for the further power increase? 3. Is there any issues using TDD mode in LMS6002D? We've been using onnly FDD mode so far and it would be great to know what issues could we expect when switching to TDD mode. -- Regards, Alexander Chemeris.
