For wide range input signal level, it needs to use the synchronous detection circuit shown in the figure 16-1 if you want to get linear detector output. First it uses PLLICNE565 to make a moving signal that is the same with input signal n/2. Then it uses multiplier ICMC1496 and phase shift signalling to switch the input signal. After full-wave rectification, it can get detected output signal, moreover, because the rectification action works with input signal, the detected circuit has frequency selectivity.
