In 2023 i built a transverter for this frequency using du3t preamp and sspa. the transverter is yo4hfu, which is an excellent design. the beauty of this band is the availability of sspa’s with some 50watt rf power. characteristics of the bounced signals are comparable with those found on 10ghz.

Yo4hfu projects last update: 31.01.2026 coming up under development 24ghz rf signal generator & tg downconverter 76ghz transverter filtronic ta402 403 tracking generator 3 26.5ghz for hp8563a. Transverter 5760mhz to 144 432mhz using modern parts. this is the last updated version of 5.7ghz transverter. adjustments are not required due to ceramic band pass filters. excellent image and lo rejection, all spurious are less than 53dbc if 144mhz 1w output. rx 1db compression point at 36dbm 5760mhz, gain 28db.

In order to reuse 23ghz wavelab for 24ghz ham radio band, suitable power supply, lo and 2nd frequency conversion to 144 432 are required. next project can solve this issue, it is not the most simple design but a different approach. monitoring of output power, internal temperature, 12v power supply voltage. Together with yo4rhy, we succeed to reverse engineering & testing the board. rx tx pll chains are identically, only the frequency range is different, both are designed around lmx2326 pll ic and patented low phase noise vco (s53mv). internal vco tuning lock range: rx = 2310 2540mhz, tx = 2160 2348mhz.
