Abstract
A transmitter comprises an antenna array demultiplexor having a first input for an output signal, a second input for a control signal, a first output coupled to a first output pin, and a second output coupled to a second output pin. The antenna array demultiplexor provides the output signal to the first or second output based on the control signal. The first and second output pins are coupled to first and second antennae, respectively. In some implementations, the transmitter includes a transformer and a capacitor coupled in parallel between the first and second output pins, and the antenna array demultiplexor comprises a first switch coupled between the first output pin and a first ground pin, and a second switch coupled between the second output pin and a second ground pin. The first switch receives a second control signal, and the second switch receives an inverse of the second control signal.
