Denelex stocks Hybrids / Couplers that offer unique flexibility and cost advantage to many microwave and RF applications. The product features the performance characteristics of octave band 3dB quadrate hybrids 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. The features include:
- Octave band performance
- Formability
- Low Loss- Low Cost
- Available in Bulk 5 ft length, Cut & Trimmed Straight, Cut & Trimmed formed and Connectorized Lengths
- Aerospace and Commercial Heritage
- ROHS compliant (Tin Plated & Bare Finishes Only)

NOTE: Electrical specifications summarized in the table above are determined by measurements at 300 MHz in 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 derated linerly to 50% at 105 c and to 0 to 155 c.

OUTLINE DRAWING
COMPUTING THE LENGTH OF CUT & TRIMMED:
To determine the length “L” of a 3dB quadrature hybrid:
- Compute quarter wavelength frequency (center frequency of your band of use) as follows:
- Fq (MHz) = (fmin +F max) / 2
- Compute the hybrid length “L as follows:
- “L” (inches) = 1850 / Fq (MHz) or “L” (Centermeters) = 4700 / Fq (MHz)
