I am in the process of designing an SDR and have completed a block diagram of its architecture. Before proceeding with more thorough component identification, I was hoping to receive confirmation that the architecture is "sound." Epic success? Epic fail? Is there anything else that you would add/remove? etc.
Notice that I have at least identified the LT5516 and LTC5599. My plans are also to include a power detector for forward and reverse power detection. Dashed lines represent digital information, most likely via SPI. SPDT RF switches will be controlled via the DSP depending on whether the SDR is receiving or transmitting.
Any thoughts would be greatly appreciated!
