More Information
Summary:An indirectly heated phase change switch (IPCS) for radio frequency (RF) switching, comprises two RF ports and an RF path therebetween, a phase change material (PCM) located between the RF ports, an embedded heater separated from the PCM by a dielectric layer, the embedded heater configured to provide thermal actuation of the PCM to bring about phase changes between a crystalline state and an amorphous state to provide Ohmic switching, and a bias voltage on the IPCS across said RF path. The bias is provided during heating to improve the crystallization time.
