What is the best image rejection currently available for a Low IF architecture receiver?
ploy-phase filter and quardrature multiplier
The answer depends on signal bands and frequencies, but roughly can be said that in mass production 30 dB can be achieved without any calibration and 40 dB with calibration.
the larger the bandwidth is and higher freqs go in direction of decrease the achievable result.
I hope it can help.
