Abstract
A radio frequency (RF) switching circuit includes stacked phase-change material (PCM) RF switches. The stacked PCM RF switches can include a high shunt capacitance PCM RF switch having its heating element contacts near its PCM contacts, and a low shunt capacitance PCM RF switch having its heating element contacts far from its PCM contacts. An RF voltage is substantially uniformly distributed between the high shunt capacitance PCM RF switch and the low shunt capacitance PCM RF switch. The stacked PCM RF switches can also include a wide heating element PCM RF switch having a large PCM active segment, and a narrow heating element PCM RF switch having a small PCM active segment. The wide heating element PCM RF switch will have a higher breakdown voltage than the narrow heating element PCM RF switch.
