Wireline and Wirepac quadrature couplers and hybrids, developed and patented by Sage Laboratories, consist of a pair of wire center conductors surrounded by a continuous dielectric insulator and shielded by a drawn or extruded metallic jacket. The resultant construction has the physical attributes of semi-rigid coaxial cable and the electric performance of a precision TEM mode parallel coupled line coupler. Electrical Performance includes frequency independent quadrature output phases, low VSWR, low insertion loss, high directivity and freedom from intermodulation products. Installation options include drop-in, surface mount as well as several conventional cable attachment approaches. Although the product is not pick-n-place compatible, it continues to be used in many moderate volume applications due to its performance and flexibility advantages. The product boasts a considerable aerospace heritage and is fabricated using military grade materials and processing.
The Wirepac® family of products offer the advantage of Wireline® design technology in a lower loss higher power capability package. The product features the performance characteristics of an octave band 3 dB quadrature hybrids in a construction similar to semi-rigid cable. Installation options include drop-in, surface mount and flange mounted alternatives. Although the product is not pic-n-place compatible, it continues to be used in many moderate volume applications due to its performance and flexibility advantages.
