Mini Octave-Band Couplers

MINI-LINE ™ Series Mini Octave-Band Couplers feature Stripline construction using single and multi-section designs and provide standard power sampling up to 50 watts CW in miniature coaxial packages that have proven performance and reliability and can operate under extreme environmental conditions. These mini octave band directional couplers meet most industry standard footprints and mounting configurations. Couplers exhibit good directivity, excellent primary line and coupled port VSWR.

These directional couplers are designed and tested to meet most military specification requirements. Performance tests may include Thermal Shock, Thermal Cycling, Temperature-Altitude, Vibration, etc. Couplers meet all facets of ISO 9001, MIL-STD-201F, MIL-Q9858A and MIL-STD-45662.
