Abstract

Aspects of this disclosure relate to a very low intermediate frequency (VLIF) receiver with multi-decade contiguous radio frequency (RF) band coverage. Non-quadrature local oscillator (LO) signals drive mixers. The non-quadrature signals can be generated from low noise digital dividers having non-traditional division ratios. The non-traditional division ratios can be prime number ratios such as 5 and 7. The systematic non-quadrature nature of the LO/mixer can be subsequently corrected by a deterministic I-Q coupling network prior to complex signal processing.
