Design and Implementation of High Power Amplifier for IMT-2000 Repeater
초록
In this paper, we made 5W 2stage power amplifier for IMT-2000 repeater. We designed this amplifier by harmonic balanced simulation using nonlinear model to minimize distortion. After simulation, we acquired 47㏈m 1㏈ compression point at 2110 ~ 2170MHz single tone input. In addition, the ACPR of this amplifier was good. The test result was 47㏈m 1㏈ compression point, 42.6㏈ gain, -36.16㏈c ACPR at 2.5MHz, -44.34㏈c ACPR at 5MHz and -51.67㏈c ACPR at 7.5MHz.
