Mirny is a 4 channel wide-band PLL/VCO-based microwave frequency synthesiser.
Like the Urukul DDS Synthesiser but with a VCO/PLL (ADF5356) as the synthesizer and options for frequency double/tripler and analog frontend mezzanines.
Comparing Mirny to Urukul:
- Much larger frequency range (53 MHz to >4 GHz vs. ~1 MHz to 500 MHz in the first Nyquist zone for Urukul). Up to 13.6 GHz when using the mezzanine.
- Much higher frequency resolution.
- Lower jitter and phase noise.
- No linear high resolution output amplitude setting (c.f. AD9910 ASF).
- No deterministic phase control, no coherent or absolute phase changes.
- Large frequency changes are not "agile" (take a few ms) and do not have high timing resolution; small frequency changes (<10kHz)canstillbemaderapidly.
- RF switch changes or attenuator changes still benefit from high timing resolution through the EEM connector.
