Figure 8 - Variation in NF with Input Amplitude (typical)
The output of the RF AGC stage is coupled to the quadrature mixer where the RF input is mixed with quadrature LO
(local oscillator) signals generated by the on-board LO.
2.2.2 Baseband
The mixer outputs are coupled to the baseband quadrature channel amplifier and filter stage, which is of 7th order
topology. Operation and control of the baseband filter is contained in “Baseband Filter” on page 17.
The baseband paths are DC coupled, and include a DC correction loop. The high pass characteristic for the DC
correction loop is defined by the off chip capacitor connected to pins ‘IDC/IDC’ and ‘QDC/QDC’. The output of each
channel stage is designed for low impedance drive capability and low intermodulation and can be loaded either
differentially or single-ended; in the case of single-ended load the unused output should be unloaded. The
maximum output load is defined in the electrical characteristics table.
