Abstract: Example embodiments of the invention are directed to CMOS differential antenna switches with multi-section impedance transformation. The differential architecture can provide relief from large voltage swings of the power amplifiers by distributing the voltage stress over the receiver switch with two of the identical or substantially similar single-ended switches. In order to reduce the voltage stress further, multi-section impedance transformations can be used. Degraded insertion loss due to the impedance transformation technique can be compensated by selecting an optimal impedance for the antenna switch operation. Accordingly, the use of the multi-section impedance transformations with the differential antenna switch architecture enables high power handling capability for the antenna switch with acceptable efficiency for the transmitter module.
