Abstract
A SPDT switch includes an antenna port. A transmitter section is coupled to a transmitter port. The transmitter section includes a plurality of transistors that are coupled in series relative to each other. A receiver section is coupled to a receiver port. The receiver section includes a plurality of transistors that are coupled in series relative to each other, so that when the transmitter section transmits high power to the antenna port, the receive section is effectively off to provide isolation to the receive port. The receiver port is coupled to the receiver section using at least one external capacitor. The at least one external capacitor is used to improve the power handling capability and harmonic performance of the switch.
