New broadband microwave combiners for high power solid state amplifier systems

A new range of broadband microwave combiners for use in HPAs for applications including automotive EMC testing has been launched by Link Microtek. These combiners enable high power, broadband and low loss combination of microwave signals with performance not achieved by other methods such as Wilkinson. For example, the AMRC-8-7/16 is a 3-6GHz, eight-way combiner offering loss of only around 0.3dB while able to combine powers with output up to 1000W easily. The device is a radial design with eight N-type input ports and one 7/16 output port. Since the design is reciprocal, it can be used as a power splitter as well. The unit is only (190mm long x 6mm diameter and weighs 1.1kg. It is fabricated in aluminum.
