  • RE: TRF370417: FSK using TRF370417

    Resolved
    Kang-san, I shielded the oscillator and separated it from TRF370417 and got a good signal.

  • TRF370417: IF Harmonics issue

    Part Number: TRF370417 Hello all, I'm currently working on a design using the modulator as an SSB upconverter. My input for IF is 16 MHz, my LO is 607 MHz to generate 591 MHz. By adjusting the IF level, pots R4, & R2 I'm able to calibrate out the…

  • TRF370417: Baseband VCM and Maximum Input Level

    TI Thinks Resolved
    Part Number: TRF370417 Hi Experts, We have this query from client about VCM tolerance for TRF370417. The datasheet for the TRF370417 gives the IQ base band input common mode voltage as 1.7V. What is the tolerance on this? Also the TRF370x Evaluation Module…

  • TRF370417: Phase shifter and distortion

    TI Thinks Resolved
    Part Number: TRF370417 Hi Team, Our customer is looking at the TRF370417 as a vector multiplier/modulator and want to confirm the IQ phase shifting capability over the entire 0.05 - 6GHz configuration. He would like to know if the phase can be shifted…
