amplifier station
解釋
放大站-
Test results show that under 2 - tone test in 5mhz tone spacing, the power amplifier system achieves - 50dbc imd3 with 20w output power, improved 20db in imd3 compared with the one without linearity. estimated value of aclr comes to 53db, which satisfies the 3gpp requirement for wcdma base - station transistor. further tests with alterative input power indicate a steady suppression to the imd3 controlled by the adaptive system
