The frequency drift is severe, perhaps because the OCXO never reaches the preset temperature？ssb should not be a problem

Part of the 6cm PA plan, then a suitable 3db90 degree bridge needs to be found to complete the power synthesis，The final stage is TIM5359-45L, and the front stage is a device without any identification

The internal structure of the local oscillator LO1 and LO2, LO1 is 11GHz, and the mixing of LO2 and 1.45GHz produces 12.45GHZ, which is provided to the transceiver front-end component

12.45GHzLO is fed separately through power distribution.1. Triple mixer to PA, 2.RX downconverter. Then it can be determined that TX is near 37.35GHz (no confirmation of TX intermediate frequency)
