Hi SM,
SM said: We also checked the dc levels on them at R62 and R54 with respect to ground. One of them was at 1.37V and the other at 2.11V. Could this be affecting it?
This is quite extreme. Given the DAC to TRF is AC coupled, there must be some…
Part Number: TRF372017 Hi sir,
The customer wants to DC combine and single ended drive the baseband input of TRF372017,
but there is no sample on the data sheet.
If you have reference information or circuit diagrams, can you share them and give…
Part Number: DAC3484 Other Parts Discussed in Thread: TRF372017 , Hello,
Please advise on a dc-coupled interface circuit between DAC3484 and TRF372017?
I assume that in-order to correct IQ imbalances and LO leakage we will need a dc-coupled interface…
Part Number: TRF372017 Hi Team,
We would like to ask your help regarding the customer's inquiry below.
I am working on an application where I need deterministic (phase) behavior between multiple TRF372017. Sadly the TRF features different frequency…
Shota-san,
I will need your reference input to the TRF372017 for the PLL. I will also need the baseband output frequency of your DAC + the actual LO frequency being used to generate the plot.
I used the assumption of the LO = 500MHz. With such LO…
Part Number: TRF372017 Hello all,
I'm measuring a 30 dBm loss on the RF output at 473 MHz. Possible problems: over heated while soldering, 1uf diff pair caps measure 0.8uf.
Has anyone experienced this type of RF loss ?
Surprisingly, the ATSC modulated…
Part Number: TRF372017 hi,
we have some questions on Auto Cal feature of TRF372017:
1) Which is the target nominal Vtune for the internal VCO calibration procedure for the recommended VCO_cal_REF (010) at +25C and vs temperature? Which is the relevant…
Hello Chan100,
You may download the TRF372017 EVM GUI and dump out the sequence after the GUI calculation for the register settings.
The value of sequence depends on integer or fractional mode
All status registers are available on the TRF372017…
