Space Machine offers a standard product line of double ridge waveguide to coax end launch adapters covering sizes WRD750 thru WRD200. VSWR is 1.50:1 max. Improved VSWR performance can be obtained over a reduced bandwidth. Space Machine’s End-Launch Adapters use a transition whose center conductor is structurally tied to the waveguide, for excellent mechanical and thermal stability. Additional sizes and configurations available upon request.
