Has anyone tried running DigiLite directly on 13 cm? I note that the AD8346 IQ Modulator is within spec between 800-2500 MHz.
Would it be as simple as applying a 2300 MHz oscillator, or are there other issues (the balun?)
I'm just scoping a high-level design and wondered whether I should directly generate for 13 cm or would need to mix up (from 437 MHz?).
Just out of Interest I am going to try a YIG at 23cm but the output is too high and needs dropping about 24dB this is to go into a DIGILITE PCB
No reason why you cannot get a 13cm YIG they are perfectly clean and low phase noise with no mixer elements to worry about just keep the current very stable
This is on my TODO list so will keep you informed
