    Abstract: An uplink signal attenuator, a device for attenuating and amplifying uplink signals by using the same, and an external remote controller therefor are provided to minimize unnecessary time and labor cost as well as to reduce time in finding noise occurrence points and to minimize broadcasting and internet failures. An uplink signal attenuator comprises a connection terminal, a relay, a ground resistance and an attenuator. The connection terminal, connected to a connection terminal of a remote controller, receives power from an external remote controller. The relay grounds an uplink signal inputted from an output port side band separation filter according to the power supplied by the external remote controller via the connection terminal. The ground resistance, connected to the relay, intercepts the uplink signal. The attenuator attenuates the uplink signal, outputted from the relay, to a certain level and outputs the attenuated signal to an uplink signal processor.

    Abstract: PURPOSE: A transceiver in a mobile communication base station is provided so that the mixer of a transceiver in a base station can always be operated stably. CONSTITUTION: A band pass filter(210) filters an inputted IF(Intermediate Frequency) signal. An attenuator(220) attenuates the filtered IF signal. A splitter(230) splits an inputted local signal. An attenuator(240) attenuates the local signals split and outputted from the splitter(230). An amplifier(250) amplifies the local signals attenuated and outputted from the attenuator(240). A gain compensator(260) compensates the gain of the local signals amplified and outputted from the amplifier(250). A low pass filter(270) filters the gain-compensated local signals. An attenuator(280) attenuates the local signals filtered from the low pass filter(270). A coupler(290) couples some of the local signals attenuated and outputted from the attenuator(280). An amplifier(300) amplifies some of the local signals outputted from the coupler(290). A detector(310) detects the voltage of each local signal outputted from the amplifier(300). A comparator(320) compares the local signals detected and outputted from the detector(310) and outputs them to the gain compensator(260). A mixer(330) mixes the IF signal attenuated from the attenuator(220) with the local signal coupled from the coupler(290) and outputs an RF signal. An attenuator(340) attenuates the mixed RF signal. A band pass filter(350) filters the RF signal attenuated from the attenuator(340).
