That is my design @ 24GHz with patch antennas RX & TX on board. On the picture you can see top and bottom of the front end module. Base band is quite actually. Where I can see your base band solution.
Modules are a lot. Try these HopeRF **broken link removed**, if you like Chinese. If not, here https://www.semtech.com/images/datasheet/xm1203f_ag_0108.pdf
from Swiss land.
Yes its very interesting. That is for LASER modulator?
As for baseband it has DSP configuration. FPGA core and DAC & ADC. Simply it was cheaper against real DSP.
Thanks for reply. I`m confident. More than ten years ago I quite successfully participate at same projects and we finally made own baseband on Spartan FPGAs . Now it`s same problem, but configuration should be little bit different. Ethernet interface and semi duplex RX-TX like WiFi protocol...
Hello!
Does any body has idea concerning 4FSK base band realization for data transmuting.
Main parameters: full or semi duplex? data whitening, programmable bandwidth, up to 20 MHz and data transmitting speed up to 20-30Mb/s and Ethernet interface. Probably not so big deal, I hope so.
Probably may be two orthogonal antenna, with two ports connected to a 3db coupler. In these case you can see right or left circular polarization without looses.
That one could be nice. Only input part should be advanced and smart. I`ll try.

And server would be nice, with some 8 GPU nVIDIA Kepler cards and RAM 64Gb and price up to 100K$:razz:

Max number of GPU for CST. And than the whole nirvana.

and for zombies as well...
Much better but with some limitations of course. That staff is in narrow band. Circulators has limitations as well, I have a lot experiences, but they are more wide with not so big rejection with depends from matched
ports. No matching no isolation . 8-O No pain, no gain.
