  • Patent number: 11323075
    Abstract: An envelope tracking (ET) amplifier apparatus is provided. The ET amplifier apparatus includes a distributed ET integrated circuit (DETIC) configured to generate a distributed ET voltage. The DETIC may be coupled to a higher-bandwidth (HB) amplifier circuit and a lower-bandwidth (LB) amplifier circuit configured to amplify an HB radio frequency (RF) signal and an LB RF signal, respectively. In examples discussed herein, the DETIC may be configured to selectively provide the ET voltage to one of the HB amplifier circuit and the LB amplifier circuit, depending on which of the HB amplifier circuit and the LB amplifier circuit is activated. By providing the DETIC in proximity to the HB amplifier circuit and the LB amplifier circuit, it may be possible to reduce potential distortion to the HB RF signal and the LB RF signal, without significantly increasing footprint of the ET amplifier apparatus.
