TRF370417: Phase shifter and distortion

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 an entire 360 degrees given the baseband inputs and if there is a way to simulate this device.



  • Hello,

    The TRF370417 is designed to be a I/Q up conversion transmitter from baseband to RF.

    It by itself has no I/Q phase shifting capability. The user will provide baseband I/Q data for the RF upconversion. LO is injected to the multiplier circuit to perform complex I/Q multiplier for the RF conversion. 

    The given condition for I/Q signal is that the I/Q must have quadrature relationship (i.e. 90 degrees offset through Hilbert transform). 

    The external digital to analog converter (DAC) can have the phase shifting waveform for the TRF370417 for the phase shift operation, but the TRF370417 itself has no phase shifting capability.
