Model AM10000DC881 is a broadband coaxial directional coupler that operates from 2 to 18 GHz, making it a suitable candidate for applications in electronic-warfare (EW) and test-and-measurement systems. It provides 30-dB coupling over the frequency range, with coupling flatness held to ±1.4 dB. The insertion loss is less than 0.5 dB while directivity is at least 12 dB across the full frequency range. The coupler, with amplitude sensitivity of ±1 dB, can handle 400 W average power and 3 kW peak power. It exhibits mainline VSWR of 1.40:1 with branch line VSWR of 1.60:1. The coupler is supplied with TMC male connector on the mainline input port, TMC female connector on the mainline output port, and SMA female connector on the coupled output port.
