摘要：
An input interface is provided for interfacing between a radio frequency input, for example from a cable distribution network, and a plurality of radio frequency tuners. The interface comprises a broadband active multipath non-reactive power splitter (41) having an input (39) for receiving a broadband radio frequency signal and a plurality of differential outputs (17). The splitter (41) further has an active power splitting circuit which supplies the broadband radio frequency signal to each of the outputs (17) via a channel (42) comprising an automatic gain control circuit (43) having a single-ended output connected to the input of a differential output buffer (45).
