Irvine, CA. Pasternack, a manufacturer and supplier of RF, microwave, and millimeter-wave products, has unveiled a new family of instrumentation-grade directional waveguide couplers offering accurate performance up to 110 GHz. These ultrahigh frequency waveguide couplers are commonly used for signal sampling and other general-purpose applications in wireless transmit/receive systems, test benches, satellite communications systems, radar systems, point-to-point backhaul applications, and telecom systems.
In this latest release of waveguide directional couplers are 28 unique models spanning a frequency range of 18 GHz to 110 GHz in seven frequency bands, including K, Ka, Q, U, V, E, and W bands. The couplers are offered in two physical configurations, standard waveguide and split block waveguide, and are also available in both E Bend and H Bend designs. Both the traditional waveguide and split-block waveguide versions utilize a multi-hole design, which is optimal for power-reflection measurements.
Pasternack’s new couplers are offered in various waveguide sizes from WR-42 (K band) to WR-10 (W band) and come in either 10-dB or 20-dB coupling values. These waveguide couplers offer high directivity of 30 dB typical, and insertion loss is as low as 0.6 dB in some models. This family of waveguide couplers is constructed using high-quality brass copper that is gold plated for added precision and accuracy.
“Pasternack is rapidly expanding its waveguide portfolio to meet the demands of the industry, which is moving towards components at higher and higher frequencies,” said Mark Blackwood, passive components product manager at Pasternack. “While we continue to expand our entire product portfolio, one of our key strategies is to offer our customers the most comprehensive selection of in-stock waveguide components in the industry.”
