VARIABLE-POWER TRANSCEIVING DEVICE. |
摘要 |
The invention relates to a transmission or transmission/reception device having a transmission path structure which makes it possible to increase the range of variation of the transmission power without degrading the signal-to-noise ratio. The attenuation is achieved in part in an internal unit 5 and in part in an external unit 4 with the aid of a switching circuit 25 which short-circuits or otherwise the amplifier 20 of the antenna 21.
