ADL5519  SPCIE simulation module wanted

Dear enash,

         I want to use the ADL5519 for my power monitor design and then calculate voltage standing-wave ratio (VSWR) . Before I start my design, I want to do some simulation of ADL5519, but I don't find the ADL5519 Spice simulation in your office website, so if you can send me the SPICE Module or other method to finish the simulation

Thanks for your kind consideration and looking  for your early reply.

    Unfortunately, there is no SPICE model for the ADL5519, but we do have one for the AD8310, which is found on its webpage (link below).  Might this be suitable for your simulation needs?

  • Hi

          Thanks for your kind reply.

          I have used the AD8310 for the simulation and the software is ADIsimPE. The schematic and simulation result is listed as follows:  

             Input signal Vin:                 315mV 1Mhz sine wave

             the sine wave power :       Vin*Vin/50/2=1mW=0dBm

             the output voltage :         Vout = 0.024mW/dB*0--95=2.28V

    Is the input signal is correct?  The input signal include the negative signal,  I am not sure it can be negative.

    Hope you can give me the certain advice.

    Best regards,

    Shizheng Zhu

    You have the input AC coupled so the zero bias should be fine.  The input of the device is biased to roughly 3.1V.

    You should:

     - Let the offset filter pin float; this should not be grounded.  If the simulator gives an error about a DC path to ground, place a 10meg Ohm to ground on this pin

     -  Place a cap to ground on the BFIN pin to filter the output ripple; the 2*1MHz content is coming through to the output.  It talks about this in the datasheet:
