The scenario
Design of a multiband SDR receiver for concurrent reception of multiple signals using parallel I/Q paths. The architecture separates in-phase (I) and quadrature (Q) components after downconversion, with individual filtering and digitization before baseband processing.
What is in this drawing
Read the decisions behind it.
01
Use of a single local oscillator with phase shifter for quadrature generation
02
Separate low-pass filters and ADCs for I and Q channels
03
Centralized DSP for processing
Applicable when designing direct-conversion SDR receivers needing wideband capture with parallel digital processing.
