Dear Everybody,
does anyone know how to stablize a 7 GHz up-converter output signal?
The up-conversion works in two steps. 180MHz is first IF and 570 MHz is the second IF. Now we noticed a level imbalance of around +- 1.5 dB on a temperature range of +-30K.
Design is in MMIC.
The goal is +-0.2 dB in the mention temp. range.
Ideas are welcome.
