Pasternack, an Infinite Electronics brand provider of RF, microwave and millimetre-wave products, has launched double-ridge waveguide couplers featuring integrated coaxial connectors for seamless transitions in diverse applications. To meet various requirements, the couplers are available in various waveguide sizes, such as WRD-650, WRD-750, and WRD-180. In RF systems, achieving power division and combination is essential, and Double Ridge Waveguide Couplers play a crucial role in this process.

The press release says the couplers offer exceptional Voltage Standing Wave Ratio (VSWR) performance, with ratios as low as 1.25:1, ensuring efficient power transmission and reduced signal reflection for optimal signal integrity. Moreover, the line’s broadwall and loop coupler designs establish new benchmarks for broadband performance and industry efficiency standards. The integrated connector design includes SubMiniature version A (SMA), Type N, and 2.92 mm connectors, ensuring compatibility across various systems.

The company claims that the couplers provide flexibility with coupling levels ranging from 10, 30, 40, and 50dB, meeting the adaptable requirements of diverse applications. The couplers are high-performance partners who address the complex challenges that characterise the modern communications technology landscape. Reaching a maximum power rating of 400W (CW), the waveguide couplers deliver high performance even in the most demanding conditions.

Some of the key specifications of the coupler include:

  • Waveguide Size: WRD-650
  • Flange Type: Cover
  • Flange Group: Standard
  • Frequency, Min: 6.5 GHz
  • Frequency, Max: 18 GHz
  • Impedance: 50
  • Maximum VSWR: 1.5:1

“This new series shows Pasternack’s dedication to innovation and quality in RF, microwave and millimetre-wave technology,” said Product Line Manager Kevin Hietpas. “With their exceptional power rating, performance and immediate availability, these couplers not only meet the growing demands of our clients but reflect our commitment to pushing boundaries.”
