The synthesizer requirements:
7.5GHz, Phase Noise requirements: 100Hz -73, 1KHz -95, 10KHz -99, 100KHz -104
I would like to use low PN 100MHz XO (assume low enough for the app).
Can I use 10MHz Reference (100MHz/10) and fraction of 0.1x. Ie. resolution of 1MHz. What loop BW is needed.
I also need spurs -50dbc + margin
Can I get the PN and spurs performance with these settings. If not what reference is needed to get the PN.
The DS have better performance plot Fig 33 at 6GHz. What is the XO, REF, loop BW and other setting to generate that signal. Fractional or fixed.
