The DFC Series from Space Machine and Engineering are Double Ridge Waveguide Circulators that operate from 8 to 18 GHz. They have an insertion loss of less than 0.5 dB and provide an isolation of 15 dB. The circulators can handle an average input power of 250 W, peak power of 2 kW and have a VSWR of under 1.45:1. These are permanent magnet 3-port devices that use a Y-junction structure housed in standard double ridge waveguide.
