Hybrids, 3dB Quadrature, Wireline®, Drop-in & Connectorized Wireline® FEATURES • • • • • • • Octave Band Performance Formability Low Loss - Low Cost Available in: Bulk 5 ft. Length, Cut & Trimmed Straight, Cut & Trimmed Formed or Connectorized Lengths Aerospace and Commercial Heritage RoHS Compliant (Tin Plated and Bare Finished Only) EAR 99 The Wireline® family of products offers unique flexibility and cost advantage to many microwave and RF applications. The product features the performance characteristics of an octave band 3 dB quadrature hybrid in a formable construction similar to semi-rigid cable. 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.

NOTE: Electric specifications summarized in the table above are determined by measurements at 300 MHz in a matched 50 Ohm system and are independent of physical length and frequency with the exception of power. At jacket temperatures above 55°C, the power should be de-rated linearly to 50% at 105°C and to 0 at 155°C.

Compute the quarter wavelength frequency (center frequency of your band of use) as follows: Fq (MHz) = (Fmin + Fmax) / 2 2. Compute the hybrid length “L” as follows: “L” (inches) = 1850 / Fq (MHz) OR “L” (centimeters) = 4700 / Fq (MHz) Alternatively, this function is available at SpectrumMicrowave.com Recommended Installation Alternatives and Other Mounting Options: See trimming, mounting and installation guide.
