project started 07.07.2025
Version 5 "Light" - project finished
5,7 GHz transverter, Version 2 "Mini", 175 mW output
New project based on YO4HFU - Robert, 5,7 GHz transverter, Version 2 "Mini"

transverter progress 12.12.2025
PLL 5616 MHz - 2808MHz x 2
PLL 5616 MHz was made with ADF4351 module, PIC12F625 controlled for 2808 MHz
At 2808 MHz the level signal from ADF4351 module was -1.7 dB
40db RF amplifier module was used for passive doubler frequency module with HMC204 attack and another 20dB RF amplifier module for > 13dB level for mixer HMC219 from transerter
15,60 dB level at 5616 MHz very good for HCM219 mixer attack
Final measurements and adjustments
Version 5 "Mini" - project finished
Version 5 "Mini" - next step will add 5.8GHz WiFi booster - have 5W out and 15dB LNA
5GHz band test and first QSO at 10 Km distance 59++ both station
