    Description

    [0158] The invention will hereinafter be further elucidated based on the figures, wherein;

    [0159] FIG. 1 shows a perspective view of a modular amplifier according to the invention;

    [0160] FIG. 2 shows a schematic view of a modular amplifier according to the present invention, and;

    [0161] FIG. 3 shows a schematic view of an amplifier assembly according to the present invention comprising modular amplifiers as shown in FIG. 2.

    [0162] FIG. 1 shows a perspective view of a modular amplifier 1 according to an embodiment of the present invention. The modular amplifier 1 has a housing 2, which is for illustrative purposes only partly shown in this figure. The back of the housing 2 comprises a number of connections 3, 4, 5. Although the connections are shown to be positioned on the back of the amplifier 1, these could even be positioned on the front or side of said amplifier 1. One of the connections 3, 4, 5, is in particular an amplifier power input connection 3. This connection is configured for delivering power to the entire amplifier 1. Furthermore an amplifier signal input connection 4 and an amplifier signal output connection 5 are present. These are respectively for receiving at least one signal to be amplified and transfer said signal to the amplifier 1 and for delivering an amplified signal. The connections 3, 4, 5 for power, an input signal and amplified output signal are shown as single connections. However, it must be understood that there might be multiple signal input connections 4 for each receiving a single signal to be amplified. Equally so for the signal output connection 5, of which multiple could be present wherein each would thus be configured for delivering an amplified signal. It is furthermore possible to include a communication connector (not shown), such as a communication bus or including ethernet connection. All connectors may also be housed in a common connector. Inside the amplifier housing 2 (only partly shown) there is a plurality of amplifier modules 6. Each of said modules 6 is configured for amplifying at least a part of a signal. To this end, each module 6 is provided with a module power connection (not shown), for receiving power from the amplifier power input connection 3. Furthermore, a module signal input 7 and module signal output 8 connection are provided, such that each modules can receive a signal that is received by the amplifier signal input connection 4. The module signal output connection 8 delivers an amplified signal to the at least one amplifier signal output connection 5. In order to amplify signals, the modules are each provided with amplification hardware 9, wherein the amplification hardware 9 has a predetermined amplifying power. The amplifier 1 according to this figure shows 8 separate modules 6 for amplifying. However, the number of modules 6 shown in this figure is merely illustrative, and in fact any number of modules 6 can be incorporated in the amplifier housing 2.

    [0163] FIG. 2 shows a more schematic representation of the amplifier 1. It shows that the amplifier signal input connection 4 is connected to all of the module signal input connections 7, such that the controller can selectively connect the correct amplifier module 6. Only a single amplifier signal input connection 4 is shown in this figure, which could either receive a single analog signal, or a composed analog signal, wherein the composed analog signal should be decomposed before entering the respective module 6 assigned by the controller.

    [0164] FIG. 3 schematically shows a plurality of amplifiers 1 as shown in FIG. 2 inserted into an amplifier assembly 10. The amplifier assembly 10 comprises at least one assembly signal input 11, which receives at least one signal to be amplified, and is configured for sending said signal to one or more amplifiers 1. The assembly 10 comprises at least one assembly signal output 12 for delivering at least one amplified signal. Also, the amplifier assembly 10 is provided with a common power unit 13 for powering all inserted amplifiers 1. The assembly 10 has a plurality of slots (not shown) which are adapted to each receive a modular amplifier 1 according to the invention. The figure merely illustrates the connections between the components. In fact, the slots are provided with a power connector 14, wherein after the amplifier 1 is slid into the slot the power input 3 of the amplifier 1 is coupled to the common power unit 13, such that the amplifier 1 is provided with power. Also the slots comprise each a signal input and output connector 15, 16, wherein after the amplifier 1 is slid into the slot, a connection is established between the assembly signal input 11 and the amplifier signal input 4, and between the assembly signal output 12 and the amplifier signal output 5. The common power unit 13 is connected, via station 18, to all the inserted amplifiers 1 separately. The station 18 in fact configured for converting a power supplied to the power connector 13 into a power required by each amplifier. Since not all amplifiers 1 have to be loaded equally, this required power can vary. In this non limitative embodiment the assembly 10 comprises a bus 17, which is configured for directing the assembly input signal which is received by the assembly signal input 11 to the correct amplifier 1. The assembly 10 shows a total of three inserted amplifiers 1, which is only for illustrative purposes, and can in fact be any number. Each amplifier 1 is drawn with a number of 4 amplifier modules 6. That means that for this non limitative figure a total number of 12 amplifier modules 6 are available. The controller unit is configured for selectively forming groups of amplifier modules 6, wherein each group can amplify a single signal received by the assembly signal input 11. This means, that the controller unit can form a maximum of 12 groups, each for amplifying a signal. However, it might also be the case that the first amplified is fully utilized by a single signal. And that the remaining two amplifiers together amplify two more signals, one signal amplified by 2 modules 6 for example, and the remaining six modules 6 amplifying the third signal. Any combination of modules 6 can be formed, and they do not have to be in a single amplifier 1.
