CDMA RADIO BASE STATION EQUIPMENT |
摘要 |
<p>PROBLEM TO BE SOLVED: To provide a CDMA base station equipment with which the cost and size of the station can be reduced by eliminating the need for a large scale compensation circuit for removing intermodulation distortion incident to 2 carrier signal being inputted to a transmitting/amplifying section, and eliminating a distributor and a combiner for operating two transmitting/amplifying sections in parallel. SOLUTION: In the CDMA base station equipment for transmitting/receiving a plurality of RF signal, each of a plurality of transmitting/amplifying sections is arranged and connected with each of a plurality of frequency converting sections thus amplifying only one of the plurality of RF signals. Output from each of the plurality of transmitting/amplifying sections is arranged and distributed to the plurality of frequency converting sections.</p> |
