Abstract
Disclosed examples include multichannel RF transponder circuits with multiple transponder channel circuits individually connected to a corresponding antenna circuit, a configurable shared modulation capacitor, a channel switching circuit to selectively connect the modulation capacitor to a selected transponder channel circuit, and a modulation circuit to selectively change the capacitance value of the modulation capacitor between two or more values according to a modulation control signal to transmit uplink data using the selected transponder channel circuit.
