Abstract
A radio frequency (RF) switching circuit includes stacked phase-change material (PCM) RF switches. Each of the PCM RF switches includes a PCM, a heating element transverse to the PCM, and first and second heating element contacts. The first heating element contact is coupled to an RF ground, and the second heating element contact may also be coupled to an RF ground. Each of the PCM RF switches can also include first and second PCM contacts. A compensation capacitor can be coupled across the first and second PCM contacts in at least one of the PCM RF switches.
