TRF371135: Single Ended Operation without Balun

Part Number: TRF371135

I'm working on a high-bandwidth device (hoping to use the full 1.7-6GHz range) and would like to use the TRF371135 in a single-ended format on the RF side (I am ok with a balanced LO).  Most other IQ demodulators allow for a DC-blocked 50 ohm termination on one of the legs of the RF port, but I don't see any mention of this solution in the documentation.  Will this implementation not work for this chip? Due to space and complexity constraints, I can't switch through multiple baluns to cover the entire bandwidth.

  • Hi Raymond,

    I am currently looking into this and will get back to you.

  • You will not lose any bandwidth if you use the TRF371135 in a single ended format. You will, however lose some output power, and I believe that the noise figure may increase as well.
