RE: AFE7070: CPFSK using AFE7070
Hi Madan, IQ Modulation is used to suppress the side band at the output.In both cases (QPSK and CPSK) you would be using Hilbert transform to generate complex data and by using complex data you will only see single side band and the image will be suppressed...

RE: AFE7225: marine VHF wireless transceiver application
Art: The DAC samples up to 250 MSPS. 1st Nyquist zone is up to 125 MSPS. It would be tricky to transmit at 156-162 MHz within the second Nyquist zone, but possible with a reduction in output power due to SINC roll-off. The ADC samples up to 125 MSPS...

RE: AFE7071: output of AFE7071 has unexpected spurious at 0.5*LO and 1.5*LO frequency
i don't think the hardware design has some problem. yesterday the local TI FAE bring the AFE707XEVM Evaluation Module to my office, and we did some test together. the result is same. the LO frequency is 400Mhz, we use a signal generator as LO...
