I have a hackrf one sdr, which i use to transmit test signals. I am using ISM bands, so I can omit transmitting my callsign, checking correct sub band (FM, digital) etc. And one of most interesting bands is 2.4 GHz, the wifi band.
The problem is that i have only one SDR device capable of operation in that band - the hackrf itself.
But recently I have discovered a MAX2121(b) IC which I saw in a sat top box circuit diagram. And this chip is what I think I need - it downconverts frequencies from 800-2100 mhz to IQ signal.
The problem is that this chip's upper band limit is 2100 MHz, which is below 2400 MHz.
I tried to google "S band tuner ic" and found one which band starts from 2600 - still outside desired band.
So, the question is: is there any 2.4 ghz tuner ICs for SDR receivers?
