| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | An ultra low distortion class-F power amplifier for 3.5GHz base stations of broadband access systems is presented. The feature of this amplifier is an GaAs on-chip input 2nd harmonic tuning circuit placed in front of each FET unit cell to achieve the linearity under class AB operating conditions by the accurate control of input 2nd harmonic impedance. With the proposed FET, a single-chip multi-cell FET for verification exhibits a low distortion of a -51 dBc ACPR and a 19% PAE with a 11.8-dB associated gain at a 10-dB back-off output power level under a 3.5-GHz 3GPP W-CDMA signal test. This ACPR corresponds to a 10-dB reduction in ACPR of a conventional FET. In addition, a 25 W power amplifier with two proposed FET chips successfully achieves a 1.5% EVM (Error Vector Magnitude) at an output power of 34.6 dBm under a 3.5-GHz WiMAX (IEEE 802.16a) compliant OFDM signal test, where the output power is a 10-dB back-off level. | |
