8.2.1.1 Design Requirements

The primary design requirement for an IQ demodulator application is to interface a pair of passive mixers with an RF ADC. The mixers have a 0‑V common-mode voltage. The ADC requires an input common-mode voltage of 1.2 V with full-scale swing of 1.35 VPP. Choose the power supplies, and design the input/output network for the TRF1305x2 as the ADC driver amplifier, to perform the dc level shifting and amplification function.
