Mirny

Mirny microwave synthesiser extension

Mirny is a low-cost PLL/VCO-based microwave frequency synthesiser, designed for non-critical applications such as driving AOMs/EOMs.

Status: idea. not funded.

Specification

• Four channels per board if possible, two otherwise.
• No requirement for deterministic phase control or sub kHz resolution.
• To be used with external power amp if required/desired.
• SPI plus a couple TTL/CS for attenuators/RF switches. If needed with a SPI based decoder, e.g. PCA9502 8-bit I/O expander with I2C-bus/SPI interface or similar.
• Synthesizer ~40 MHz to ~4 GHz: e.g. ADF4351 (like the SynthNV) or HMC833 (apparently a convenient superset of the ADF4351).
• Frequency reference from an internal few ppm-accurate Quartz.
• Include the usual chain of (similar to Sayma AFE Allaki digital output):
  • user-mountable filters
  • pre-amp
  • attenuators
  • rf switch
  • maybe: user-mountable frequency doubler (to 8/12 GHz) or tripler/quadrupler (to 16/18 GHz)
