Tuning an R820T2 RTL-SDR up to 6 GHz via a Harmonic Mixing Driver Hack provides information about an softwarehack that allows to to use the 5th harmonic on R820T2 RTL-SDRs to receive frequencies above the normal 1.766 GHz limit https://www.rtl-sdr.com/tuning-an-r820t ... iver-hack/ .
I am wondering how well matched to 50 Ohm the frontend is above 1700 MHz and if modifications are needed.
So far I only found S11 measurements up to 1290 MHz from DG8GB "Receiver construction using 50 ohm modules (gain blocks), Part 3: 23cm version (DG8GB) at http://www.vhfcomm.co.uk/dg8gb.html.
Is anyone aware of some other links or has anyone done some modifications and/or measurements for >1700 MHz?
