Abstract

In many examples, a device comprises a transmitter. The transmitter comprises a power amplifier, a first transformer coil coupled to the power amplifier, and a second transformer coil adapted to be electromagnetically coupled to the first transformer coil. The transmitter also comprises a first bond wire coupled to a first end of the second transformer coil and adapted to be coupled to a first end of an antenna, a capacitor coupled to a second end of the second transformer coil, a switch coupled to the capacitor and configured to engage and disengage the capacitor from the transmitter, and a second bond wire coupled to the switch and adapted to be coupled to a second end of the antenna.
