Part Number: AFE7222 Other Parts Discussed in Thread: TRF370333 Dears.
customer is developing AFE7222.
AFE7222 DAC has a current output, but use Voltage input GRF6413, need Current to Voltage with Common voltage tuning. Use Transformer or using a Termination…
Thanks Ken,
The attenuation looked wrong, because the cap accross R2 was not shown (pseudo DC). Unfortunately we do use a DC output, so the
AC short circuit will not help.
I will revisit the complete DAC / modulator selection. In the mean time I will…
Other Parts Discussed in Thread: DAC5688 , TRF370333 Hi.
I got ACPR decreasing problem using DAC5688.
Fdata=122.88MHz
NCO=15.36MHz/138.32MHz
FDAC=491.52MHz
PLL off
X4 interpolation
All data is measured data at moduler TRF370333 ouput
As captured…
The TRF3703 provides improved performance compared to the TRF3701/2, specifically in the linearity parameter. There is another advantage that the TRF370333 device operates at a 3.3V common mode that mates seamlessly with the DAC568x family. There is a…
