hi everybody,
i try to design a DRO @ 9.9 GHz in ADS. all conditions for stability are satisfied and it oscillates, but the harmonic balance simulation does not look that good to me. i uploaded 2 pics, the schematic and the HB-simulation. what can i do now to improve my output signal? and why does "Vres" at the transistor input look that strange?
please help me, i would appreciate it. =)
