Magnis SDR - Part 7 Transmit Mixer
In this video I will be building the Transmit mixer which is based on the Tayloe mixer design I have shown in earlier videos such as

RDA18
rda1846-sa818-capturing-i2c-with
In this video I solder connections to the SDA and SCL lines on the SA818 board and show the resulting traffic on the scope. Then I use the I2CDriver
https://i2cdriver.com/
To capture traffic between the uController and RDA1846. I also do a quick demo of the I2CDriver itself. The resulting traffic captured is here:
https://github.com/thaaraak/rda1846/blob/master/documents/c2.csv
I did try the Bus Pirate
http://dangerousprototypes.com/docs/Bus_Pirate
but I was unable to capture the traffic (potentially because the I2C bus is running at too high a frequency)

PHASE
phaser-build-part-5-phase-shift-and-ssb
In this video I continue the Phaser build and pull together the phase shift network and RF combiner. I then test the lower sideband suppression on the spectrum analyzer.
I did check the manual and the lower sideband suppression should be -35dB down between 800-2800 Hz. I was only getting that between ~1200-1800Hz. That could certainly be related to the replacement FST3257 I put in. I will check again after the transmit stage is complete.
