We found a problem on ADRF6510 during testing with our customer. ADRF6510 has a DC +2.5V out from I/Q pin OPP1,OPM1,
OPP2 and OPM2. When we intend to control gain and inject a changed voltage into pin GAIN, the DC has a rising or falling beat then takes about 50ms go to stable. This problem results in degrading our system performance.
I also measured EVB of ADRF6510 to duplicate this problem and captured four pictures below for you reference. Do you have
similar experience to get us some suggestions ?? Thanks!!
