Z-Communications has developed a range of full-band waveguide-to-coax adapters along with precision low-powered waveguide terminations covering 5 GHz to 40 GHz and available in rectangular waveguide sizes ranging from WR137 to WR28.
The parts’ mechanical design provides full-band impedance matching with low reflection coefficients and insertion loss.
The VSWR for the waveguide adapters and terminations are better than 1,20 and 1,02, respectively. They require no extra matching or tuning element reducing the chance of arcing when used in high power applications. Furthermore to the standalone performance of the adapters series, the waveguide terminations provide power handling of 0,5 W for the WR28 covering 26,4–40,1 GHz to 2,0 W for the WR137 over the frequency range of 5,38–8,17 GHz.
The new off-the-shelf components come in precision machined aluminium with either SMA or 2,92 mm female connectors. They are offered with the industry standard square cover flange for all rectangular waveguides except for the WR137 which is available in the standard CPR flange.
