This specific DBBPF rejects the annoying frequencies of the second and third harmonics in the dual-band and contributes considerably to performance improvement of ADPA. This structure is confirmed with the design, simulation, implementation and testing of a 10 W GaN-based ADPA for global system for mobile communications (GSM) and worldwide interoperability for microwave access (WiMAX) applications at 1.84 and 3.5[Formula: see text]GHz, respectively. In the measurement results, the ADPA defines a drain efficiency (DE) of 63.7% with an output power of 35[Formula: see text]dBm and power gain is 14.2[Formula: see text]dB, and a DE of 47.5% with an output power of 34.5[Formula: see text]dBm and power gain is 10.4[Formula: see text]dB at the 9[Formula: see text]dB output power back-off (OBO) from the saturated output power in the two frequency bands. Linearity effects, applying 10[Formula: see text]MHz 16 QAM signal and a 5[Formula: see text]MHz WiMAX signal, display an adjacent channel leakage ratio of [Formula: see text] and [Formula: see text][Formula: see text]dBc with the average output power of 36.8\/36[Formula: see text]dBm at 1.84\/3.5[Formula: see text]GHz, respectively. <\/jats:p>","DOI":"10.1142\/s0218126619502359","type":"journal-article","created":{"date-parts":[[2019,1,15]],"date-time":"2019-01-15T06:12:25Z","timestamp":1547532745000},"page":"1950235","source":"Crossref","is-referenced-by-count":2,"title":["A Novel Dual-Band Concurrent Asymmetric Doherty Power Amplifier for Wireless Communications"],"prefix":"10.1142","volume":"28","author":[{"given":"Shaban Rezaei","family":"Borjlu","sequence":"first","affiliation":[{"name":"Department of Electrical & Computer Engineering, Science and Research Branch, Islamic Azad University of Ashtian, Iran"}]},{"given":"Massoud","family":"Dousti","sequence":"additional","affiliation":[{"name":"Department of Electrical & Computer Engineering, Science and Research Branch, Islamic Azad University, Tehran, Iran"}]}],"member":"219","published-online":{"date-parts":[[2019,2,11]]},"reference":[{"key":"S0218126619502359BIB001","doi-asserted-by":"publisher","DOI":"10.1109\/22.989965"},{"key":"S0218126619502359BIB002","doi-asserted-by":"publisher","DOI":"10.2528\/PIERC14012305"},{"key":"S0218126619502359BIB003","first-page":"654","volume-title":"IEEE Microwave Conf.
