Abstract: The application relates to modular electronic apparatus (1) for distribution of RF communication signals. The apparatus comprises a chassis (2) arranged to removably receive plural modules (3), at least some of which are arranged to receive and process RF communication signals. A communication path (17) is provided for modules to communicate with each other and/or with the chassis. Plural modules received in the chassis. When a module is received in the chassis, it is arranged to broadcast a message over the communication path indicating its presence in the chassis and its type. At least one other module is arranged to adapt its behaviour in response to the message.

Abstract: There is provided an RF amplifier arrangement comprising: an input operable to receive an RF input signal; an output operable to output an amplified RF signal; at least one amplifier bank located between the input and output, the or each amplifier bank comprising a plurality of amplifier stages; an input level detector operable to measure the signal level of the RF input signal; and a controller operable to control the amplifier bank, wherein the controller is operable to select one or more different configurations of the amplifier by selecting one or more amplifier stages and/or modifying one or more characteristics of one or more amplifier stages in dependence upon the signal level of the RF input signal to dynamically adapt and optimise its characteristics.
