  • Optimization of error loops in distributed power amplifiers
    Patent number: 6972622
    Abstract: Several feed-forward RF power amplifiers configured for use in a distributed array, each having a main amplifier within a carrier null loop and an error amplifier within an error loop. Each carrier null loop includes a switch configured to selectively disable the carrier null loop, thereby disabling the carrier null loop, and injecting an actual RF signal into the error loop allowing the error loop to be optimized using the actual RF signal.
    Type: Grant
    Filed: May 12, 2003
    Date of Patent: December 6, 2005
    Assignee: Andrew Corporation
