Simple Linear Amplitude Modulator with 100% Depth of Modulation
Hello, This is the first time I have used this forum so please excuse any errors in protocol. This really ought to be a trivial question but, in practice, I have found it quite tricky to pin down a...

Hi John, You want to use a true linear multiplier for this. I would suggest you look at the ADL5391. Cheers Ed

Thanks Ed, that is really helpful. It is a bit high current (130mA) but this shouldn't matter for my particular application.John

I've fixed the second error. DMA_WIDTH is a localparam in the Verilog source. For some reason Vivado did not recognize it and did not apply the calculated width, instead replacing it with a width of 1.

Re: AD9361 : RX and TX using the same LO
Hi,tlili As you replied, the Local Freqencies of TX and RX parts can be set to different values, can't they?But the BBPLL is unique for both RX and TX parts, which means it works for both parts. Does...
