The F.A.Q. page was added.

Watch for the Neon Project news on twitter !

28.06.2010

The RF Unit schematics is added (check the Downloads section). The schematics is incomplete, the full one will be available after mixer article publishing in QEX - look for the Jul/Aug 2010 QEX issue!

The RF Unit page was updated.

I have got the DSP chips! So now I am ready to start building the Neon's DSP Unit. It will be based on the Freescale dual core Symphony DSP56720.

24.03.2010

The PA Unit schematics is added (check the Downloads section).

23.03.2010

The PA Unit page is added. The initial measurements are good. I will put the detailed measurements results after completion of the LPF Unit.

13.02.2010

The IF Unit schematics is added (check the Downloads section).

I connected temporarily the Neon's IF Unit to the ADC on the DSP Unit of the T03DSP transceiver and was able to measure parameters in quadrature mode. The full story is on the IF Unit page.

So now I need to design an ultra low noise synthesizer to match the Neon's RF fontend performance (the calculated IMD3 DR values are 107dB inside roofing filter and 116dB outside). The goal is to reach the synthesizer sideband noise better then -140dBc/Hz@1kHz and -150dBc/Hz@10kHz - that will be a real challenge!..

The IF Unit is on the test bench (read more...).

The Control Unit hardware is almost ready. The new SOS3 real time OS (based on the SOS/SOS2 RTOS) runs nicely on the STM32F103ZET6 (Cortex-M3 core). I have to write a lot of the new code and port some old one (from the T03DSP) yet, but you can view some pictures here already.

The links page was added. It will contain links to useful articles, related projects, datasheets of the used ICs and various tools involved in the design process.

The BPF unit description and Downloads section were added.

I started to fill the BPF & RF units pages...

A small update.
