  • RE: TRF3705: Is it possible to drive TRF3705 BB inputs directly from a FPGA ?

    Nir, For simple BPSK, you can design the level shifter circuit to reduce the amplitude of the CMOS output to appropriate bias level of 0.5V VCM with the proper swing, and I agree you can achieve the interface requirement. The design of the TRF3705 has…

  • TRF3705: Maximum bandwidth of the IQ modulator output RF signal

    TI Thinks Resolved
    Part Number: TRF3705 Other Parts Discussed in Thread: TRF370417 Hi Team, The TRF3705 IQ modulator datasheet states that its 1-dB input frequency bandwidth is 1000MHz. Does this IQ modulator output RF signal with a bandwidth of up to 2000MHz? Thanks, …

  • TRF3705: Base band input DC properties

    Resolved
    Part Number: TRF3705 Q1 We intend using the TRF3705 in an application where the baseband signal is only about 50kHz and coming from a micro via some circuitry. All the examples show 50R resistor to ground on these inputs. In our application burning 4…

    Part Number: TRF3705 Other Parts Discussed in Thread: TRF37T05 , HI This is HS KOH in WS. I have question. I think TRF3705 and TRF37T05 are simillar to specification. What is the difference between TRF3705 and TRF37T05. Please let me know. Thanks, H…

  • TRF3705: TRF3705 Input/Output Level

    Part Number: TRF3705 Other Parts Discussed in Thread: DAC3482 Hello I'm Alber as a FAE in Arrow Korea. My customer use DAC3482 & TRF3705. My customer has a question about TRF3705 Input/Output Level as aspect of RF Level. IQ Modulator has 4 input…

  • TRF3705: de-embedded s-parameters

    Part Number: TRF3705 Hi Team, One of my colleagues is looking for the de-embedded S-parameters for the TRF3705. I found this post: but it doesn't seem to match this app note: Do they need to be de-embedded? Also, was the gain set to high or low on…
