A high-frequency signal combiner comprising four bridge decouplers (1'; 1") in order to transform in each case two input-end, high-frequency signals (IN1, IN2) into in each case four high-frequency signals (OUT1, OUT2, OUT3, OUT4), each having at least approximately identical power, and a bridge coupler in order to add the total of 16 high-frequency signals (OUT1, OUT2, OUT3, OUT4,...) of the four bridge decouplers (1'; 1"), wherein each bridge decoupler (1'; 1") consists of four bridge branches (11; 11', 11", 11'''), wherein each bridge decoupler (1'; 1") has in each case a connection in a diametrically opposed bridge branch (11, 11''') of the bridge decoupler (1'; 1") in order to feed the respective two input-end high-frequency signals (IN1, IN2), for which in each case one input-end high-frequency line is provided, and wherein in each case two parallel or serial connections (13', 13'') are provided in order to output four high-frequency signals (OUT1', OUT2', OUT3', OUT4'), in each case in diametrically opposing further bridge branches (11', 11") of the bridge decoupler (1'; 1") in each case for an output-end high-frequency line, wherein each high-frequency line contains an inner conductor and an outer conductor, wherein each bridge decoupler contains four bridge nodes, wherein in two bridge nodes in each case an inner conductor of the input-end high-frequency line and in each case an inner conductor of the two parallel or serial switched output-end high-frequency lines (13', 13") are connected in a bridge node, and wherein in two further bridge nodes in each case an outer conductor of the input-end high-frequency line and in each case an outer conductor of the two parallel or serial switched output-end high-frequency lines (13', 13'') are connected in a bridge node, wherein a single bridge node connected to the outer conductors is placed to ground potential, wherein in each case two diagonally opposed bridge nodes form a bridge diagonal, wherein in each bridge diagonal in each case one load balancing resistor (ZLAW) is provided, and wherein each high-frequency line connected to the bridge decoupler has in each case an annular core for sheath wave decoupling; wherein the bridge coupler contains four bridge branches (4, 4', 4", 4"'), wherein each bridge branch (4, 4', 4", 4''') in each case is formed by a bridge diagonal of in each case one of four sub-bridge couplers, wherein in the bridge diagonals (10, 10', 10", 10''') formed orthogonally from the bridge branches (4, 4', 4", 4''') of each sub-bridge coupler in each case one load balancing resistor of the respective sub-bridge coupler (R2, R3, R4, R5) is provided, wherein in each case two bridge nodes of each sub-bridge coupler are connected in a bridge node (A, B, C, D) of the bridge coupler, wherein in each case one bridge node (F, G, H, I) of each sub-bridge coupler forms the four diagonal corner points of the high-frequency signal combiner, wherein in the individual bridge branches of the four sub-bridge couplers in each case one connection is provided for a high-frequency signal of the bridge decouplers, wherein the bridge decouplers (1', 1") are embodied such that the outputs in the parallel arranged bridge branches of each sub-bridge coupler and parallel arranged bridge branches of in each case diagonally opposed sub-bridge couplers are in each case identical, wherein in a bridge diagonal of the bridge coupler a connection is provided at the connected bridge nodes (A, D) in order to output a sum signal from the 16 input signals, and wherein in a bridge diagonal of the bridge coupler arranged orthogonally to the bridge diagonal in order to output a sum signal, a load balancing resistor of the bridge coupler is provided.
