Hybrids, 3dB Quadrature, Wirepac®, Drop-in Wirepac® FEATURES • Octave Band Performance • Higher Power Handling Capability • Low Loss - Low Cost • Prepared Ready to Install • Aerospace and Commercial Heritage • EAR99 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. 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: For LC, KC & FA Series - “L” (inches) = 1970 / Fq (MHz) OR “L” (centimeters) = 5004 / Fq (MHz) Alternatively, this function is available at SpectrumMicrowave.com Recommended Installation Alternatives and Other Mounting Options: See trimming, mounting and installation guide.
