r&s®smw-九游官网下载

• two perfectly aligned signals (frequency, phase, timing, level) to stimulate the main and auxiliary amplifiers of a doherty pa
• power split and input-power dependent phase delta in real time
• real-time shaping functions (e.g., polynomial, shaping from table, normalized or classic doherty dog leg) on the auxiliary path
• real-time digital pre-distortion (e.g., polynomial, or from pre-distortion table with up to 4000 entries) on both paths
• graphical display of shaping and pre-distortion functions

the r&s®smw-k546 digital doherty software option sets up the r&s®smw200a to automatically generate two precisely aligned signals (frequency, time, phase and amplitude) to stimulate the main and auxiliary amplifier inputs of a doherty pa.

it performs power split and input-power dependent phase delta on the two signal paths in real time. advanced features include in-built shaping functions (e.g., polynomial, shaping from table or classic doherty dog leg) for the auxiliary path as well as real-time am/am and am/pm digitial pre-distortion on the main and auxilliary signal paths.

the r&s®smw-k546 digital doherty software option works seamlessly with the r&s®fsw-k18 amplifier measurements application on the r&s®fsw signal and spectrum analyzer to fully characterize doherty amplifiers, providing the designer with an in-depth understanding of performance trade-offs and information to select the best input split for any doherty amplifier design and application.
