on another topic, there's a good chance i can forget about the (external) mixer and just use the transceiver directly. the 2360 - 2400 band runs a biiit close to the 2.3GHz lower limit of the bandpass...

some other good news is that the transceiver has an integrated analog RSSI output, which is wired to the MCU's ADC channel 1. takes only a couple chips to settle, I could sample it on every received PSDU octet and take the mean or something. frees some machinery in the FPGA and as a bonus it's also taken before the VGA, so I would only need to take the LNA setting into account

in sadder news, the HackRF Pro isn't really designed to allow the FPGA to do AGC :( the transceiver's gain control pins B1..7 are unconnected so I'd need to go through the MCU and then the 20MHz SPI interface
