Our customer is using the LT5581 to detect 3.5GHz TDD RF signal.
But at different modulation of the input signal, there is much difference in the detector value(about 5dB error).
She tried to tune for improvemnet but could not.
- Frequency : 3.6GHz
- Input signal modulation : LTE20M TM1.1 and LTE20M TM2.0
- Input Power : -10dBm.
I am looking forward to your advice for inproving performance.
Note)She is also using the LTC5582 and this part has not difference in detector values depending on the different modulation of input signal.
