$begingroup$ A transmission line balun is a suitable option for 180 degrees shift at 350 GHz. Capacitors only ''shift by 90'' when comparing current to voltage. You need to involve other components to shift voltage to voltage, then the shift per cap becomes less than 90.

About Photovoltaic Energy StorageIn the two-stage architecture of 48 V data center power systems, the front-end intermediate bus converter (IBC) needs to adapt to both 48 V nominal input voltage and a wide input voltage range of the backup battery (typically 40 V–60 V). To cope with this design challenge, we propose a phase shift regulated resonant switched-capacitor …
About Photovoltaic Energy StorageThe Effect of Phase. We saw in the previous page that the voltage across a capacitor is delayed relative to the current: when a voltage source is first connected to an RC circuit, the current through the capacitor reaches its maximum value right away, but the voltage drop gradually increases toward the maximum value.
