  • TRF371135: TRF371135 SPI Communication

    Part Number: TRF371135 Tool/software: Hello I have a device where the TRF371135 is used, according to the documentation I have all 4 Registers of the Device should be written. I measured a quite awkward behaviour of the SPI Interface. Yellow…

  • TRF371135: Common mode voltage range

    TI Thinks Resolved
    Part Number: TRF371135 Other Parts Discussed in Thread: ADS62P49 , TRF371109 , TRF371125 , , TRF3710 The datasheet is mostly silent on the VCM pin, except when it is contradictory. The pin definition is "B aseband common-mode input voltage ", implying…

  • TRF371135: Gain Clarification and Noise Figure Model

    Resolved
    Part Number: TRF371135 I am confused as to what the typical gain is for this. In the datasheets I see graphs relating the gain to the LO and not RF, which seems a bit odd to me, with gain around 40 dB. Is using the LO reference for the gain the proper…

  • TRF371135: Single Ended Operation without Balun

    TI Thinks Resolved
    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…

  • TRF371135 Minimum RF Input Signal

    Other Parts Discussed in Thread: TRF371135 Hello, could somebody tell me the minimum RF input signalpower, the TRF371135 needs to mix a 5.8GHz signal down to zero? Thanks a lot. Best Regrads, Benedikt Neidlein

  • RE: TRF371135: TRR371135 as a Phase Detector?

    Actually, the offsets might cancel out. The phase is the arctan of I/q www.markimicrowave.com/.../

  • Output of IQ from TRF371135

    Other Parts Discussed in Thread: TRF371135 Hi I have purchesed a evaluation board of TRF371135 for implementing zero IF receiver. In board resistor is set in 2G5. so my RF signal is centered at 2.5GHz having bandwidth of 16MHz. I am controling the…

  • Connecting TRF371135 (IQ demodulator) and LMH5401 (Active Balun)

    TI Thinks Resolved
    Other Parts Discussed in Thread: LMH5401 , TRF371135 Hi, I'm using the LMH5401 (as an active balun 2-3GHz) as an input device for the TRF371135 (IQ demodulator). Both need to be powered using a 5V single-supply. That gives me a common-mode voltage of…
