This process introduces a 90 [degrees] phase difference between the RF and LO signals applied to the mixers and produces two in-phase/quadrature IF outputs that are of equal magnitude.
An advantage of sampling with the in-phase/quadrature approach over a single-ended design is that, for the same instantaneous bandwidth, the ADC can operate at half the clock rate of a single-ended design, which increases the ADC effective number of bits and provides better performance.
0 frequency range (GHz) IF 3 dB bandwidth (MHz) [+ or -] 15 IF 15 dB bandwidth (MHz) [+ or -] 25 In-phase/quadrature amplitude imbalance (dB) [+ or -] 0.
The detected in-phase/quadrature differential video signals are fed to the ADC section through plated through holes.
