  Abstract

The car DAB (Digital Audio Broadcasting) receivers have the external LNA(low noise amplifier) for improved sensitivity. And usually the external LNA is controlled depending upon the state of the wanted signal level only. There is the possibility that the wanted signal station is far away with the weak signal level and the adjacent channels station is located in near area with the strong signal level. At this moment, if the external LNA is maintaining the high gain status, the signal of the adjacent channel will act as unwanted noise in the wanted band. It can cause the reception performance degradation. At this time, if the gain of the external LNA is controlled adequately by detecting the adjacent channel level, it is useful to avoid the reception performance deterioration due to the linearity of the external LNA. And it is possible to maintain the inherent performance of the DAB receiver.
