High-yield tunable radio frequency (RF) filter with auxiliary capacitors and non-volatile RF switches

A high-yield tunable radio frequency (RF) filter comprising:

• a plurality of process-dependent capacitors;
• a plurality of non-volatile RF switches, wherein each of said plurality of process-dependent capacitors is connected to at least one of said plurality of non-volatile RF switches;
• wherein said at least one of said plurality of non-volatile RF switches is a phase-change material (PCM) RF switch including a PCM and a heating element underlying said PCM;
• first electrical connectors above said PCM coupled to said PCM;
• second electrical connectors below said heating element coupled to said heating element;
• an auxiliary capacitor in said plurality of process-dependent capacitors being engaged by an ON-state non-volatile RF switch in said plurality of non-volatile RF switches;
• a primary capacitor in said plurality of process-dependent capacitors being disengaged by an OFF-state non-volatile RF switch in said plurality of non-volatile RF switches.
