Hi all guys,
I designed a board with microcontroller and CC1000 sub GHz transciever from TI. Since the receiver part is not intended for receiving ASK signals, additional circuitry is needed in order do derive ASK symbols from RSSI signal. In order to do that, I combined circuit from MAX1471 datasheet where and the principle is shown here:
It is also recommended to select resistors and cpacitors values as following:
What I don't get here is what should peak-detector combining network be? If they mean RC between PDMAXA and PDMINA then I have R and R in series and C and C in series which will lead to RC. Is this meaning of combines circuit.
My circuit looks like this:
Thanx and cheers

The maximum and minimum peak detectors can be
used together to form a data-slicer threshold voltage at
a midvalue between the maximum and minimum volt-
age levels of the data stream (see the Data Slicers sec-
tion and Figure 5). The RC time constant of the peak-
detector combining network should be set to at least 5
times the data period.
