Hello,
In the datasheet of TRF370417, we have the Adjusted Carrier Feedthrough vs Frequency from 60MHz to 80Mhz (Figure 22) and after from 900MHz to 1GHz (Figure 23). No information between. Is it possible to have…

Hi Hruday,
We are using our custom board for measuring.
When we are using LO frequency of 2024.5MHz and IF of 400MHz and 500MHz, we are observing side band suppression lesser than 30dBc.
Thank you.

Hi,
My customers are working on a RF signal generator design and plan to use TRF370417 and are facing some problems about the carrier feedthrough and sideband suppression, details are as below:
As in the schematic…
Hi,
I'm checking TI IQ modulator TRF370417 and trying to see if it's possible to use this IC at frequencies lower than its typical range (50MHz to 4GHz). I wish to use it at LO 10MHz (base band signal less than 10kHz). Does TI have…

Hello, i want to connect TRF370417 with a vector modulator. From my understanding all i have to do is connect the TRF370417 IQ pins with the corresponding IQ pins on the vector modulator. My problem is that the TRF370417…
Hello,
We are looking to using the TRF370417 IQ in some signal generation. We would like to measure the effect of the device on phase noise by feeding a very clean LO. My issues is, the device requires a differential input for the…
Kang-san,
Thanks for the reply.
I think this user guide is how to manually adjust Carrier Suppression and Sideband Rejection.
Please ensure there is a dynamic loop to change the DC offset over temperature and time.
Do you have any references…
Kang-san,
I shielded the oscillator and separated it from TRF370417 and got a good signal.
