A Analog Inputs

Out of the two ADC inputs, one input, INA is driven by Differential Amplifier TRF1208 which is a 10 MHz to 8 GHz amplifier with a gain of about 16 dB. The other input INB is driven by a passive balun MTX2-73+ that has a bandwidth of 2 GHz to 7 GHz. This balun has a typical Insertion Loss from 0.6 dB to 1.9 dB.

Table A-1 provides the different settings for setting the analog inputs path.
