The filter circuit is coupled to present a filter capacitance to the first RF port and to the second RF port. The second switch device is configured to present a device capacitance to the second RF port when a common port of the second switch device is shunted to ground. The first switch device is configured to present approximately the filter capacitance and the device capacitance to its common port. The device capacitance from the second switch device can thus be used to tune a total capacitance presented to the common port of the first switch device. As such, the total capacitance presented to the common port of the first switch device can be maintained substantially unchanged without requiring a substantial increase in the number of switching components."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radio frequency front end architecture with a switch topology for routing filter circuits while substantially reducing variations in the reactive loading at common ports","description":"Radio frequency (RF) front end circuitry is disclosed that includes a filter circuit, a first switch device, and a second switch device.
