SYSTEM AND METHOD FOR A MULTI-BAND TRANSMITTER

摘要

In accordance with some embodiments of the present disclosure, a multi-band transmitter comprises a plurality of band paths with each band path configured for a different frequency range. Each band path comprises a modulator configured to modulate a data signal onto a carrier signal associated with the frequency range of the band path to generate a radio frequency (RF) signal associated with the band path and frequency range of the band path. Each band path also comprises a step-down balun that includes an input coil configured to receive the RF signal from the modulator. Each band path further comprises a tuner configured to tune the input coil to the frequency range of the band path. The tuner is also configured to compensate for off-state conduction of switches of the tuner to reduce non-linear tuning effects of the balun associated with the off-state conduction.
