10GHz WBFM transceivers

The modern way of getting (simply) into 10GHz WBFM appears to be using very low cost 10GHz Doppler radar modules with a 100MHz FM receiver. Whilst with G6ALB for my Pixie tests Andrew demonstrated a working 10GHz link based on these low cost modules. These are useful links Andrew sent me.
Hi Roger,These are the units I found when I was looking for [definitions of] the 10.525 GHz ISM band.It looks like 3cm Doppler radar is alive and well,I’d assumed it had disappeared in favour of PIR.Some data here:These are very good pages (for wideband FM on 10 GHz).
