| 摘要 |
The invention relates to a transmission configuration for continuous-time data transmission, whereby at least one programmable amplifier (7, 14) is provided in the baseband (1) or in the high frequency path (3) in the signal processing chain of the signal to be transmitted, instead of the standard automatic gain control means which is controlled by continuous-value control signals. The inventive configuration is characterised in that the signal controlling the programmable amplifier (7, 14) is a discrete-value signal. By eliminating costly digital-analog converters, the cited principle enables the current consumption of CDMA transmitters to be significantly reduced. |
