摘要： The present invention discloses a remote radio unit and a base station system. The remote radio unit includes an active part and a passive part, where the active part and the passive part are placed respectively on an active module and a passive module that are independent of each other and the active module and the passive module are connected via a pluggable connecting device. Because the passive part is more reliable and less liable to breakdown than the active part, when the active part needs to be repaired, it is unnecessary to dismantle the entire unit. Therefore, the repair is easier and faster and the repair cost is lower. The operation reliability of the base station system is also improved.

The VCO is be powered by a supply voltage applied across the first and second supply nodes. The oscillation transistor and the biasing network are connected in series between the first supply node and the second supply node. The output node is connected to the oscillation transistor so as to deliver an oscillatory output signal. The feedback network provides an oscillatory feedback signal from the output node to the biasing network. The feedback network comprises a capacitive element and a transmission line connected in series for transferring the feedback signal. The VCO may be integrated in a radar device, for example.
