| Popis: | International audience; This paper presents a performance evaluation of a class-E switched-mode power amplifier, designed in pHEMT GaAs technology, loaded by a high-isolation and low-Insertion Loss (IL) duplexer. This duplexer is based on Surface Acoustic Wave (SAW) technology. Measurements of the duplexer and layout of the class E PA are simulated under Agilent-ADS with a Wideband Code Division Multiple Access signal (WCDMA) in the 1.92 - 1.98 GHz band, for transmission scenario. In this band the amplifier alone achieved 75% to 82% efficiency and 23.5dBm to 24.2dBm output power. The association of the amplifier and the duplexer permitted to reach a drain efficiency of 78% while the output power is 22.7dBm at the central frequency, in the WCDMA band a minimum of 60% efficiency and 21dBm output power is maintained. |
