Hello, I am trying to understand the 'actual' gain in TwinRX. Experimentally, I see that a 0 dBm input requires gain of +46 dB to give a full-scale (-1/1) output. Interestingly, the two channels have about 3 dB of difference in gain (I would have expected a lot less). Since the A/D expects about 0 dBm (based on the datasheet), it appears we only have 50 dB of actual gain available. Is that correct? What does the 95 dB of gain mean?
Thanks. _______________________ Eugene Grayver, Ph.D. Aerospace Corp., Sr. Eng. Spec. Tel: 310.336.1274 ________________________
