TRF370417EVM: Power supply for the board

Part Number: TRF370417EVM
Other Parts Discussed in Thread: TRF370417

Hi Team,

Our customer bought a TRF370417EVM to do IQ modulation of a microwave signal that he use to manipulate a spin qubit. He has the following questions about the 5V power source for the board:

1. Do you recommend a power source model? 

2. What is the required stability to avoid disturbing the output signal? Can I just build something crude from a phone charger-like device? 



  • Hi Danilo,

    1. we recommend high quality bench supplies like the Keysight E3634A

    2. The power supply to the TRF370417 should be low noise and low ripple. LDOs like TPS7A83 would be a good choice. I am not sure the purpose of the question regarding the phone charger-like device. If I misunderstood the question, please let me know
